A SIMPLE METHOD FOR EVALUATING THE STATIC INTERACTION BETWEEN A PILE GROUP AND A FOOTING GROUP IN AN ELASTIC HALF-SPACE

Abstract

In this paper, we study a simple method for evaluating the static interaction between a pile group and a footing group on an elastic half space. As this simple method, we formulated closed form approximations. We evaluated the approximations by comparing them with the analytical solutions.

As a result of the study, we concluded that our approximations are sufficiently accurate for use in practical engineering (error ratio is less than 12 % in our evaluation), provided that the width of the pile group is large enough for pile length in the pile group.
