INDEX

–  –  –

This book is intended to cover and explain design practices and building code requirements for the design of earth retaining structures. It is for both the practicing engineer who has become a bit rusty on this complex subject, and for the engineering student who has already acquired a basic knowledge of statics, soil mechanics, and the design of simple masonry and concrete structures. Design review agencies will also find it a useful reference.

Why It Was Written

The design of retaining walls is not an every-day design task. During my many years of providing technical support for Retain Pro software it became increasingly apparent that many engineers infrequently design retaining walls and need some brushing-up, particularly on code requirements. It is also for the civil/structural engineering student to supplement other texts with current design practices and building code requirements.

Although there is a considerable amount of technical information available, it is widely scattered in numerous textbooks and technical papers on soil mechanics, foundation engineering, concrete design, masonry design, and in all sorts of related topics. Despite the many references, a single volume on retaining wall design for the professional practitioner and civil engineering student could not be found.

Hence this attempt to condense, simplify and compile information from many sources, including my own experience, into this book. Hopefully, it will ease your comfort level when designing retaining walls and give you a good overview of the process. For those who want to dig deeper into particular topics a comprehensive bibliography is attached in Appendix H.

Scope of This Book

This book treats design practices for most types of earth retaining structures: conventional cantilevered retaining walls: restrained (basement) walls, gravity walls, and segmental retaining walls both gravity and with geogrids. Other topics include sheet pile walls, tilt-up retaining walls, soldier pile walls, gabion walls, counterfort walls, pilaster walls and walls with pile or pier foundations. A review of basic soil mechanics is also included in this book and the appendix offers useful information including a glossary of terminlogy.

We’ll welcome your feedback. You can contact us at hbrooks@hbapublications.com.

This tenth edition, like its predecessors, become necessary because building codes change – seismic design requirements for example – and as we receive suggestions for topics to be added or expanded. To respond, successive editions have been updated, corrections made and additional materials added. All design examples have been reviewed, corrections made where needed and explanations added. A glossary of terminology has been added to this edition.

Another effort for this edition was to explain many of the topics in more detail so it will be helpful to the engineering student who may be using it as a text. We believe civil engineering students can benefit by learning building code requirements and design practices used by experienced engineers.

This series of editions began in 1996 as a modest companion manual to accompany my work developing Retain Pro software. In successive editions it has grown from 93 pages to 250 in this tenth edition, with many thousands of copies in print.

My objective in each edition was to cover basic design principles and practices in a concise, readable, manner. This book is not an in-depth treatment of the design of retaining structures. Earth retaining structures and soil mechanics are far too complex a subject to treat in a single concise volume. There are dozens of foundation engineering texts and countless technical papers available for review, and of course there is the Internet. However, finding what you need is time consuming; hence this compendium. The challenge was to decide what to put in and what to leave out and to put in the most helpful things a designer – and an advanced engineering student -- need to know to design most types of earth retaining structures. Surely there will be omissions and errors, but the intent is that you will find this book helpful in your practice.

We express appreciation to the many of you who have offered valuable suggestions, corrected errors, read portions of the draft, and faxed informative articles and excerpts from technical papers. My thanks to each of you. We will all benefit from your input.
