Engineering Method of Calculating Injection Pile Settlement in Clayey Soils

Abstract

An engineering method of calculating the ultimate settlement of a single hanging injection pile of length from 3 to 5 m in clayey soils, including weak soils, is proposed. The method takes into account the linear and nonlinear dependences of the settlement on the external load and is based on taking into account the operation of the bottom end and the lateral surface of the injection pile. The obtained results can be used to solve the complex problem of evaluating the deformations of individual and strip foundations after they are strengthened by injection piles in the reconstruction of buildings as well as new construction.
