Development of Improved Guidelines for Analysis and Design of Earth Retaining Structures.

摘要

Earth retaining structures shall be designed to withstand lateral earth and water pressures, the effects of surcharge loads, self-weight of the wall, and earthquake loads. These are the safety requirements. In addition, earth retaining systems shall be designed to provide adequate structural capacity with acceptable movements, adequate foundation capacity with acceptable settlements, and acceptable overall stability of slopes adjacent to walls. These are the serviceability requirements. The tolerable levels of lateral and vertical deformations are controlled by the type and location of the wall structure and surrounding facilities.
