DYNAMIC MODELING AND RESPONSE OF SOIL-WALL SYSTEMS

This paper presents a brief review of the inaccuracies that can result from the use of a popular model for assessing the dynamic soil pressures and associated forces induced by ground shaking in a rigid wall retaining an elastic stratum. Following the review, the sources of the inaccuracies are identified and a modification is offered, which while retaining the attractiveness of the original model, defines correctly the action of the system. In the proposed modification, the soil stratum is represented by a series of elastically supported, semi-infinite horizontal bars with distributed mass. The concepts are presented via reference to a fixed-based wall retaining a homogeneous elastic stratum and then are applied to the analysis of more complex soil-wall systems. Harmonic and transient excitations are considered. Also, comprehensive numerical solutions are presented that illustrate the actions of the systems investigated and the effects and relative importance of the many parameters involved.
