Abstract：The soil-pile-raft interaction problem with consideration of soil rheology is studied by Biot consolidation theory and integral equation method. By using integral transform methods，the fundamental solutions of ring load on the surface of the half space are established. The second kind of Fredholm integral equation of the pile-soil-raft interaction problem is obtained by using fundamental solutions and the pile-soil and raft-soil deformation compatibility condition. The integral equation can be simplified by means of Laplace transforms methods. By the numerical solution of the integral equation and the corresponding inverse integral transforms，the displacement，axial force，pore pressure along the pile axis，and the contact normal stress between raft and soil，are obtained.
