This is a combination of two book for two different types of retaining walls. For tall, flexible anchored tieback walls: In practice, the procedures used to design flexible tieback wall systems... More > differ from those used to design stiff tieback wall systems. In the design of flexible tieback wall systems, apparent pressure diagrams are commonly used to represent the maximum loads the tieback wall system might experience during construction. Apparent pressure diagrams used in an equivalent beam on rigid supports analysis are demonstrated in this report. Analyses are performed for flexible wall systems in both cohesionless and clay soil. For tall, stiff tieback walls: Methods used in the design of flexible and stiff tieback walls are described. Methods applicable to the design of stiff tieback wall systems are illustrated by example. Important in the design of stiff tieback wall systems is the consideration of construction sequencing effects.< Less

For many years, engineers have designed foundations, walls and culverts for highway and other applications using allowable stress design (ASD) methods. In ASD, all uncertainty in loads and material... More > resistance is combined in a factor of safety or allowable stress. For most highway design, the American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications for Highway Bridges represents the primary source document for ASD of substructures. In 1994, AASHTO approved Load and Resistance Factor Design (LRFD) in the LRFD Highway Bridge Design Specifications. In LRFD, the uncertainty in load is represented by a load factor and the uncertainty in material resistance is represented by a resistance factor. Due to the fundamental differences between the substructure design process by ASD and LRFD, this course has been developed to present the fundamentals of LRFD for the geotechnical design of highway bridge substructures.< Less

In 1970 "sex, drugs and rock 'n roll" ruled supreme in Point Collina, a tony beachside resort. No where was that more true than at the local high school, and that scene was ruled by Denise... More > Kendall, tennis captain and daughter of the most prominent man around. But this happy life of "peace and love" was rudely interrupted when Madeleine des Cieux, a foreign student, started to perform miracles, including healings and throwing tennis matches. Now the school, the government and Denise herself are forced to scramble for damage control, not only with Madeleine but with her ex-boyfriend, Jack Arnold, itching for revenge, and her perennial enemy, the development heiress Terry Marlowe. Both disaster and triumph end up on everyone's plate in a world which is being rapidly reshaped both by and for the participants.< Less

This book presents information on the design of retaining walls and inland and coastal flood walls. Retaining walls are defined as any wall that restrains material to maintain a difference in... More > elevation. A floodwall is defined as any wall having as its principal function the prevention of loading of adjacent land. Not specifically covered in this book are seawalls which are defined as structures separating land and water areas, primarily designed to prevent erosion and other damage due to wave action. They are frequently built at the edge of the water, but can be built inland to withstand periods of high water. This book also describes procedures for the design of retaining and flood walls on shallow foundations, i.e., those bearing directly on rock or soil.< Less

This book deals with the soil mechanics aspects of the design of waterfront retaining structures built to withstand the effects of earthquake loadings. It addresses the stability and movement of... More > gravity retaining walls and anchored sheet pile walls, and the dynamic forces against the walls of drydocks and U-frame locks. It also contains one of the most complete descriptions of lateral earth pressure theory available anywhere. The effects of wall displacements, submergence, liquefaction potential, and excess pore water pressures, as well as inertial and hydrodynamic forces, are incorporated in the design procedures. Several new computational procedures are described in this report.< Less
