Retaining Structures

UPDATED AND EXPANDED NEW 11TH EDITION. Design guide for earth retaining structures covers nearly every type of earth retaining structure: cantilevered, counterfort, restrained (basement walls), gravity, segmental, sheet pile, soldier pile, and others. Current building code requirements are referenced throughout. Topics include types of retaining structures, basic soil mechanics, design of concrete and masonry walls, lateral earth pressures, seismic design, surcharges, pile and pier foundations, Gabion walls and swimming pool walls. Fourteen varied design examples. Comprehensive Appendix with Glossary of terminology. 257 pages. 8-1/2x11 paperback.

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. It is written for practising geotechnical, civil and structural engineers; and forms a reference for engineering geologists, geotechnical researchers and undergraduate civil engineering students.

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.

Budhu presents the basic concepts and fundamental principles that engineers must know to understand the methods utilized in foundation design by exploring the values and limitations of popular methods of analyses in foundation engineering.

For practising civil and structural engineers in the field of general earth-retaining structure theory, this work presents the results of many case studies of actual retaining wall analysis, design, and construction. It also includes fundamental papers dealing with the effects of groundwater on passive earth pressure, and other related topics.

The Engineering of Foundations, Slopes and Retaining Structures rigorously covers the construction, analysis, and design of shallow and deep foundations, as well as retaining structures and slopes. It includes complete coverage of soil mechanics and site investigations. This new edition is a well-designed balance of theory and practice, emphasizing conceptual understanding and design applications. It contains illustrations, applications, and hands-on examples that continue across chapters. Soil mechanics is examined with full explanation of drained versus undrained loading, friction and dilatancy as sources of shear strength, phase transformation, development of peak effective stress ratios, and critical-state and residual shear strength. The design and execution of site investigations is evaluated with complete discussion of the CPT and SPT. Additional topics include the construction, settlement and bearing capacity of shallow foundations, as well as the installation, ultimate resistance and settlement of deep foundations. Both traditional knowledge and methods and approaches based on recent progress are available. Analysis and design of retaining structures and slopes, such as the use of slope stability software stability calculations, is included. The book is ideal for advanced undergraduate students, graduate students and practicing engineers and researchers.

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.

Models for structural analysis are needed in order to design safe and reliable soil-retaining structures. This study evaluates numerical models, mostly based on finite element techniques. This book provides a frame of reference for verification and validation of these models.
