Pile Groups Displacement Calculation Based on Mindlin Solution and Principle of Minimum Potential Energy

Abstract

A displacement function of a single pile among pile groups was proposed according to Mindlin solution. Using variational theory and principle of minimum potential energy and considering the relation between shear stress of soil around piles and displacement described in Randolph single pile displacement solution, the relation between soil and settlement in the tip of a pile was derived. Relation between load and displacement of a single pile among pile groups was obtained. It was compared with other examples after that. The result calculated by the method proposed here matchs closely with the result calculated by other methods.
