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.
