SETTLEMENT OF REINFORCED SAND IN FOUNDATIONS

The technique of reinforcing soil for foundation improvement is well e stablished. This paper addresses the aspect of settlement of reinforce d sand foundations, where the major part of the existing work deals wi th the aspect of bearing capacity. A detailed analysis is made paying individual attention to soil, reinforcement, and the interface between the two. A three-dimensional, nonlinear finite-element analysis is pr esented that uses a three-dimensional, nonlinear soil-reinforcement in terface friction element, along with other three-dimensional elements to model the system, The results of the analysis are compared with tho se from tests conducted in the laboratory and are found to be in good agreement. The studies lead to a better understanding of the behavior of the system at different stages of loading.
