Foundation and Pile Interaction with Swelling Soil

Abstract

The paper provides the results of experimental studies pilot studies of the moisture transfer and clay soil swelling characteristics and their mathematical description. An analytical solution is suggested to determine a stress-strain behavior within a body of soil with non-uniform moisture content interacting with underground structures (foundation, pile, etc.). It is shown that the swelling pressure depends on the type of the stress-strain behavior of soil, and under the compression conditions, exceeds the corresponding swelling pressure under the finite-width foundation base by several times. It was found that the pull-out force of the pile greatly depends on the modulus of deformation of the swelling soil, influence zone and pile diameter.
