摘要：
The behavior of a pile group is solved using the finite element method, and the fundamental solution of saturated multilayered soils with anisotropic permeability is obtained by the analytical layer element method. Based on the supposition of no slip occurring at the pile-soil interface, the governing equations of the interaction between the pile group and the soils due to a point sink are established in the Laplace-Hankel transformed domain by considering the pile-soil compatibility condition. Numerical results are presented to study the effect of point sink pumping, the properties of soils, and the geometries of piles on the behavior of the pile group.
