Simplified Approach to Estimate Lateral Load on Drilled Shafts Resulting from a Heavily Loaded Adjacent Shallow Foundation Using Horizontal Stress Isobars

Abstract

AbstractGrowing urbanization is leading to more structures being constructed close to each other, resulting in substantial interaction between their foundations. Although the interaction between two shallow foundations and between piles in a pile group has been studied by several researchers, the effects of interaction between shallow and deep foundations are not very well understood or studied. Not much published literature is available for practicing engineers to analyze and design shallow and deep foundations that are constructed adjacent to each other. The second author of this paper was recently involved in a project in which a structure designed to be supported on drilled shafts was supposed to be constructed adjacent to another structure designed to be supported on a large mat foundation with high floor load. Although the authors have performed a detailed parametric study using finite-element techniques to better understand stress distributions and develop a simplified method to analyze this type o...
