GRA VITY RETAINING?WALL

1. INTRODUCTION

Retaining walls are structures used to provide stability for earth or other material where conditions disallow the mass to assume its natural slope, and are commonly used to hold back or support soilbanks,coal or ore piles, and water.

Retaining walls are classified, based on the method of achieving stability, into six principal types (Fig.1). The gravity-wall depends upon its weight, as the name implies, for stability. The cantilever wall is a reinforced-concrete wall that utilizes cantilever action to retain the mass behind the wall from assuming a natural slope. Stability of this wall is partially achieved from the weight of soil on the heel portion of the base slab. A counterfort retaining wall is similar to a cantilever retaining wall, except that it is used where the cantilever is long or for very high pressures behind wall and has counterforts, which tie the wall and base together, built at intervals along the wall to reduce the bending moments and sheers. As indicated in Fig.1c, the counterfort is behind the wall and subjected to tensile forces. A buttressed retaining wall is similar to a counterfort wall, except that the bracing is in front of the wall and is in compression instead of tension. Two other types of walls not considered further are crib walls, which are built-up members of pieces of precast concrete, metal, or timber and are supported by anchor pieces embedded in the soil for stability, and semigravity walls, which are walls intermediate between a true gravity and a cantilever wall.

Figure.1 Types of retaining walls: (a) Gravity walls of stone masonry, brick, or plain concrete. Weight provides overturning and sliding stability; (b)

cantilever wall; (c) counterfort, or buttressed wall. If backfill covers counterforts, the

wall is termed a counterfort; (d) crib wall; (e) semigravity wall (small amount of steel reinforcement is used); (f) bridge abutment.

Bridge abutments (Fig.1f) are often retaining walls with wing wall extensions to

retain the approach fill and provide protection against erosion. They differ in two major respects from the usual retaining wall in:

1. They carry end reaction from the bridge span.

2. They are restrained at the top so that an active earth pressure is unlikely to develop.

Foundation walls of buildings including residential construction are retaining walls

whose function is to contain the earth out of basements.

Retaining walls must be of adequate proportions to resist overturning for (or excessive

tilting) and sliding as well as being structurally adequate.

Terms used in retaining-wall design are shown in Fig.2. Note that the “toe ” is both

the front base projection and the forward edge ; similarly for the “heel ”.

2. COMMON PROPORTIONS OF GRA VITY WALL

Retaining-wall design proceeds with the selection of tentative dimensions, which are then analyzed for stability and structural requirements and are revised as required. Since this a trial process, several solutions to the problem may be obtained, all of which are satisfactory. A computer solution greatly simplifies the work in retaining-wall design and provides the only practical means to optimize the design.

Gravity-wall dimensions may be may be taken as shown in Fig.3. Gravity walls, generally, are trapezoidal-shaped but also may be built with broken backs. The base other dimensions should be such that the resultant falls within the middle one-third of the base. The top width of the stem should be on the order of 0.30m.If the heel projection is only 100 to 150mm, the Coulomb equation may be used for evaluating the lateral earth pressure, with the surface of sliding taken along the back face of the wall. The Rankine solution may also be used on a section taken through the heel. Because of the massive proportion and resulting low concrete stresses, low-strength concrete can generally used for the wall construction.

A critical section for analysis of tensile flexure stresses will occur through the junction of the toe portion at the front face of wall.

3. GRA VITY W ALL FORCE

The forces on a gravity wall are as indicated in Fig.4.The active earth pressure is

computed by either the Rankine or Coulomb methods. If the Coulomb method is used, it is assumed that there is incipient sliding on the back face of the wall, and the pressure acts at the angle of wall friction δ to a normal with the wall. The Rankine solution applies to Pa acting at the angle β on a vertical plane through the heel. The vector can then be added to the weight vector of the wedge of soil W between the vertical plane and back of the wall to get the direction and magnitude of the resultant Pa on the wall. The vertical resultant R acting on the base is equal to the sum of the forces acting downward, and will have an eccentricity e with respect to the geometrical center of the base. Taking moments about the toe,

If the width of the base is B, the eccentricity of the base can then be computed as x B e -=2

Exploring Filipino School Counselors’ Beliefs about Learning Allan B. I. Bernardo [Abstract] School reform efforts that focus on student learning require school counselors to take on important new roles as advocates of student learning and achievement.But how do school counselors understand the process of learning? In this study, we explore the learning beliefs of 115 Filipino school counselors who indicated their degree of agreementwith 42 statements about the process of learning and the factors thatinfluence this process.A principal components analysis of the responses to the 42 statements suggested three factors:(F1)social-cognitive constructivist beliefs, (F2) teacher-curriculum-centered behaviorist beliefs,and (F3) individual difference factors.The preliminary results are briefly discussed in terms of issues related to how Filipino school counselors’ conceptions of learning may guide their strategies for promoting student learning and achievement. [Key words]beliefs about learning, conceptions of learning, school counselors, student learning, Philippines School reform efforts in different parts of the world have focusedon students’learning. In particular,most school improvement programsnow aim to ensure that students acquire the high-level knowledge and skills that help them to thrive in today’s highly competitive globaleconomy (e.g., Lee & Williams, 2006). I n this regard, school reform programs draw from various contemporary theories and research on learning (e.g.,Bransford,Brown, & Cocking, 1999; Lambert & McCombs, 1998).The basic idea is that all school improvement efforts should be directed at ensuring students achieve high levels of learning or attainment of well-defined curricular objectives and standards.For example, textbooks (Chien & Young, 2007), computers and educational technology (Gravoso, 2002; Haertnel & Means, 2003;Technology in Schools Task Force, 2003), and educational assessment systems (Black & Wiliam2004; Cheung & Ng, 2007; Clark, 2001; Stiggins, 2005) are being reconsidered as regards how they can effectively provide scaffolds and resources for advancing student learning. Likewise,the allocation and management of a school’s financial resources are assessed in terms ofwhether these are effectively mobilized and utilized towards improving student learning (Bolam, 2006; Chung & Hung, 2006; Retna, 2007). In this regard, some advocates have also called for an examination of the role of school counselors in these reform efforts (Herr, 2002). Inthe United States, House and Hayes (2002) challenged school counselors to take proactive leadership roles in advocating for the success of all

Wall Street Take a Dive Ronald Reagan’s 1985 budget took a thunderous shelling last week. Day after day, jittery Wall Street investors fired sell orders, hitting stock prices with their heaviest declines since 1982. Testifying in Washington, Federal Reserve Chairman Paul V olcker fired the single most damaging salvo by warning that the deficits envisaged in the budget pose a “clear and present danger”, threatening to keep interest rates high and tip the economy into a new recession. The size of the deficits is staggering. Rudolph Penner, director of the Congressional Budget Office, predicted that if policy is not changed, the flow of red ink will swell from $190 billion this year to $326 billion by 1989. In testimony on Capitol Hill, the President’s men acknowledged that the economy was in danger. Chief Economic Adviser Martin Feldstein, known as the Administration’s “Dr.Gloom,”agreed with Penner’s warning that the deficit could reach the $300 billion range by the evd of the decade. If that happened, said Feldstein, federal borrowing would be swallowing 75% of American savings and putting powerful upward pressure on interest rates. Even Treasury Secretary Donald Regan, usually an optimist and a critic of Feldstein’s dour outlook, admitted that “without proper fiscal and monetary policies, there is a possibility of our slipping back into a recession in the U.S.”Unless the Federal Reserve speeds up growth of the U.S money supply , warned Treasury Under Secretary Beryl Sprinkel, a recession could start this year. 译文：华尔街股价下跌 罗纳德里根1985财政年度的财政预算，上周遭到了猛烈的抨击。华尔街的投资者深感不安，每天都要下令抛售股票，压低股票价格，导致1982年以来最大幅度的下跌。联邦储备局主席保罗沃尔克在华盛顿作证时，放了最厉害的一炮。他告诫说：从财政预算中可以预见的赤字，带来“清清楚楚的、实实在在的危险”，使得利率居高不下，使得经济失去平衡。 赤字数额高得惊人。国会预算审议室主任鲁道夫彭纳语言：如果政策不改变，赤字的泛滥将从今年的一千九百亿美元，增至1989年的三千二百六十亿美元。 总统的幕僚在国会作证时承认，经济处于危险状态。总统的首席经济顾问马丁费尔斯坦，人称政府中的“忧郁博士”，他赞同彭纳提出的告诫：至80年代末，赤字将达到三千亿美元这一幅度。费尔斯坦说，如果出现这一情况，联邦政府的举债将耗去美国人积蓄的75%，产生强大的压力是利率上涨。财政部长唐纳德里甘本来是个乐天派，对费尔斯坦的忧郁观点常持批评态度，可是就连他也承认：“没有正确的财政金融政策，美国可能再度陷入经济衰退。”财政部次长贝利尔斯普林克警告说：如果联邦储备局不加速美国的货币供应量，今年就会出现经济衰退。

Such models can be built quickly and both the sketch dimensions and location dimensions are particularly useful for making the adjustments necessary to fit the various body pieces together.The parametric models then must be joined together as one geometric solid model in order to obtain a surface mesh.Structural optimization input data can then be seamlessly and quickly created from the parametric-modelbased finite element model to begin the tradeoff studies.This integrated process in which parametric modeling was coupled with structural optimization was used to carry out design studies on the lightweight body front structure.Several carbon fiber material combinations were studied to determine mass reduction potential of certain types of carbon fiber products considered to be lower cost than typical carbon fiber materials used in the past.Structural optimization was used to compare several composite constructions for the design of the bonded front structure.Eight cases were studied using various materials and composite lay-ups.Mass savings estimates from45–64%over steel were obtained.The most reasonable design consisted of a combination of relatively low cost chopped carbon fiber and woven carbon fiber and using a20mm balsa core in the top of the shock tower area. This design had a maximum thickness of7mm and a mass reduction over steel of approximately62%.Correspondence and offprint requests to:Mark E.Botkin,Principal

嘉兴学院课程论文 2012—2013学年第1学期 课程名称：英汉互译 班级：姓名：学号： 要求：阅读下文，并组织4个同学将其译为汉语（请注明每位同学翻译的部分） A Short History of Western Translation Theory Introduction Antoine Berman has argued that because "reflection on translation has become an internal necessity of translation itself…(t)he construction of a history of translation is the first task of a modern theory of translation" (Berman 1992: 1). This paper gives a very brief overview of the history of western theories of translation, from the perspective of the end of the twentieth century. The framework for my discussion will be a discourse analysis approach to the history of ideas developed by the French historian Michel Foucault. Adapting Steiner (1998: 248-9), I will divide the history of discourse on translation into four periods: (1) a "traditional" period, from the beginning of the Christian era to the end of the eighteenth century, which is a period of "immediate empirical focus", (2) a period of "theory and hermeneutic inquiry", growing out of German Romanticism around the beginning of the nineteenth century, (3) a "modern" period, reaching well into the twentieth century, in which the influence of General Linguistics is increasingly dominant, and (4) the contemporary period, subsequent to the publication of Steiner"s book, which has taken to itself the name of "Translation Studies". An Approach to the History of Ideas My sources to the end of the nineteenth century will be drawn from Douglas Robinson"s Western Translation Theory(Robinson1997a). In studying the history of ideas about translation theory, we are seeking to make sense of a series of existing written texts - what they have to say about the act of translation and translated texts, and how they say what they have to say. Clearly there is a vast amount of discourse about the practice and significance of the act of translation. The 334 pages of Robinson"s book include 124 texts by 90 authors. The historical "sequel", which is the basis of my later remarks, Venuti"s Translation Studies Reader (2000), includes 30 essays by 30 authors and covers 524 pages. This mass of documents is far from being a random collection of statements. As Foucault has noted: "we know perfectly well that we are not free to say just anything, that we cannot simply speak of anything, when we like or where we like; not just anyone, finally, may speak of just anything" (Foucault 1972: 216). Specific fields of discourse are organised in regular ways and grow out of definable social contexts. In all fields of discourse, including those related to translation, "discursive practices are characterised by the delimitation of a field of objects, the definition of a legitimate perspective
