Effectively Calculate the Pressures of Soil When it comes to designing and constructing retaining structures that are safe and durable, understanding the interaction between soil and structure is at the foundation of it all. Laying down the groundwork for the non-specialists looking to gain an understanding of the background and issues surrounding geotechnical engineering, Earth Pressure and Earth-Retaining Structures, Third Edition introduces the mechanisms of earth pressure, and explains the design requirements for retaining structures. This text makes clear the uncertainty of parameter and partial factor issues that underpin recent codes. It then goes on to explain the principles of the geotechnical design of gravity walls, embedded walls, and composite structures. What’s New in the Third Edition: The first half of the book brings together and describes possible interactions between the ground and a retaining wall. It also includes materials that factor in available software packages dealing with seepage and slope instability, therefore providing a greater understanding of design issues and allowing readers to readily check computer output. The second part of the book begins by describing the background of Eurocode 7, and ends with detailed information about gravity walls, embedded walls, and composite walls. It also includes recent material on propped and braced excavations as well as work on soil nailing, anchored walls, and cofferdams. Previous chapters on the development of earth pressure theory and on graphical techniques have been moved to an appendix. Earth Pressure and Earth-Retaining Structures, Third Edition is written for practicing geotechnical, civil, and structural engineers and forms a reference for engineering geologists, geotechnical researchers, and undergraduate civil engineering students.

"Retaining structures form an important component of many civil engineering and geotechnical engineering projects. Careful design and construction of these structures is essential for safety and longevity. This new edition provides significantly more support for non-specialists, background to uncertainty of parameters and partial factor issues that underpin recent codes (e.g. Eurocode 7), and comprehensive coverage of the principles of the geotechnical design of gravity walls, embedded walls and composite structures.

The objective of this investigation was to improve current design procedures for predicting earth pressures on rigid (concrete) conduits and retaining walls of the type frequently built by the U.S. Army Corps of Engineers. A comprehensive literature review was made to determine the generally accepted design methods (in addition to those of the Corps of Engineers) for predicting earth pressures on rigid conduits and retaining walls. Finite-element computer studies were performed to investigate the nature of earth pressures on buried conduits. Analytical comparisons were made of the many theories available for predicting earth pressures on retaining walls. Several suggested improvements to present Corps of Engineers design methods resulted from this study. The recommended procedures were compared with earth pressure data from several Corps of Engineer projects. In general, the suggested changes resulted in more accurate predictions of earth pressures on rigid conduits and retaining walls than are calculated by the present methods. This investigation has indicated several areas of inadequate present knowledge that could warrant further field and/or analytical study.

Structures placed on hillsides often present a number of challenges and a limited number of economical choices for site design. An option sometimes employed is to use the building frame as a retaining element, comprising a Rigidly Framed Earth Retaining Structure (RFERS). The relationship between temperature and earth pressure acting on RFERS, is explored in this monograph through a 4.5 year monitoring program of a heavily instrumented in service structure. The data indicated that the coefficient of earth pressure behind the monitored RFERS had a strong linear correlation with temperature. The study also revealed that thermal cycles, rather than lateral earth pressure, were the cause of failure in many structural elements. The book demonstrates that depending on the relative stiffness of the retained soil mass and that of the structural frame, the developed lateral earth pressure, during thermal expansion, can reach magnitudes several times larger than those determined using classical earth pressure theories. Additionally, a nearly perpetual lateral displacement away from the retained soil mass may occur at the free end of the RFERS leading to unacceptable serviceability problems. These results suggest that reinforced concrete structures designed for the flexural stresses imposed by the backfill soil will be inadequately reinforced to resist stresses produced during the expansion cycles. Parametric studies of single and multi-story RFERS with varying geometries and properties are also presented to investigate the effects of structural stiffness on the displacement of RFERS and the lateral earth pressure developed in the soil mass. These studies can aid the reader in selecting appropriate values of lateral earth pressure for the design of RFERS. Finally, simplified closed form equations that can be used to predict the lateral drift of RFERS are presented.

The past 10 years have seen considerable advances in the practice of retaining wall design and construction. This book makes a valuable and significant contribution to the literature available to practising civil and structural engineers, not only in the field of general earth-retaining structure theory, but also by presenting the results of a large number of case studies of actual retaining wall analysis, design and construction. The reader will find this volume particularly valuable not only because of the large number of papers reporting the behaviour of the actual retaining walls during construction and thereafter, but also because of the inclusion of more fundamental papers - for example, dealing with the effects of groundwater on passive earth pressure, and integrating the influence of shear and overturning forces in the calculation of bearing capacity), and because of the wealth of information contained on the practical aspects of the numerical modelling of retaining structures of all types.

The problem of earth pressure on retaining structures is one of the oldest in soil mechanics. This volume comprises tables which facilitate calculations in problems of limit equilibrium. These tables provide coefficients which are extreme values in which the soil still is in equilibrium. They are or

Earth retaining structures have historically performed well under seismic loading, including cases in which the structures were designed for less intense ground motion or only considering static loading. The few reported failures are often attributable to waterfront structures retaining saturated backfill where the main factor was liquefaction. The remaining failures are rare and generally involve more complex conditions, such as sloping backfill, or poor construction or design. These observations suggest that seismic design provisions for engineered retaining structures may be too stringent, and in some cases may not be necessary. The objective of this study was to extend previous efforts to understand the seismic interaction of backfill-wall systems using experimental and numerical modeling, with an emphasis on deep, stiff basement walls in cohesionless soil and the current design methods thereof. The experimental phase of the study consisted of a dynamic centrifuge model of a deep, stiff basement structure with a dry, level, dense sand backfill. The results obtained in the centrifuge experiment were first used to develop and calibrate a two-dimensional, finite difference model using FLAC2-D. A non-linear, hysteretic constitutive model was used to model the cyclic behavior of the soil and linear elastic beam elements were used to model the structure. The numerical simulations captured the most important aspects of the centrifuge experiment, specifically the inertial response and dynamic soil-structure interaction. Special attention was given to the selection of model parameters, the boundary conditions, and the initialization process. The second part of the numerical modeling effort concentrated on analyzing the response of typical prototype basement structures of varying depth using the calibrated soil properties from the first phase of numerical modeling. As would be expected, the results from the experimental and numerical analyses show that the observed seismic load increments are a function of the ground motion, wall type and the depth of embedment. The dynamic earth pressure increment distribution for deep basement structures is highly non-linear in contrast with shorter retaining structures (

Foundations and Earth Structures is written primarily for anundergraduate course in foundation analysis and design. It shouldalso appeal to graduate students and practicing engineers. Thereare three primary objectives for this textbook. Firstly, to presentbasic concepts and fundamental principles that are necessary tounderstand the background of the methods employed in foundationdesign. Secondly, to inform students on the values and limitationsof popular methods of analyses in foundation engineering. Thirdly,to provide a framework for students to carry out simple foundationdesign and appreciate the design process. This is a textbook and not a design manual. Consequently, itemphasizes fundamentals rather than procedures. However, practicalprocedures, where appropriate, are included to allow students totransit into "office" design. The topics are sequenced so as not torush the students into design but to build a solid foundation inthe fundamentals so that they could understand the implications ofthe assumptions in the design.
