THE INTERACTION BETWEEN POINT SINK AND SINGLE PILE
抽水井点和单桩的相互作用问题

In terms of Biot consolidation theory and by using integral transforms methods, the fundamental solutions of circular load or point sink in the interior of the half space are established. The second kind of Fredholm integral equation of the single pile interacted with the point sink is obtained through the fundamental solutions. The integral equation can be simplified by means of Laplace transforms methods. By the corresponding inverse integral transforms and the numerical solution of the integral equation, the displacement, axial force and the shear stress of the pile are obtained.
