Interaction Analysis Of Anchor‐Soil Systems

Abstract

Interaction analysis and understanding of the mechanism of stresses and deformations in anchor‐soil systems can require consideration of three‐dimensional geometry, nonlinear soil behavior, and relative motions at the interface. A three‐dimensional finite element procedure that can allow for these factors is proposed. It is applied for analysis of a field load test involving an anchor grouted in a sand. A general yet simple elastic‐plastic hardening model is used for the sand. The constants for this model are found from a series of laboratory tests on cubical specimens of the sand. The interface is simulated by using the thin‐layer element. The finite element predictions provide satisfactory correlation with the field observations, and are able to explain various aspects of the stress‐deformation mechanism in and around the anchor.
