Abstract

Abstract

Starting from the governing equations of Biot three dimensional consolidation problem and introducing the displacement functions,the 8 order transfer matrix between z=z and z=0 is obtained by taking the Laplace transform with respect to time(t) and the double Fourier transform with respect to coordinate x and y.According to the continuity conditions between adjacent layers and the horizon plane of well point pump and boundary conditions,the actual solutions of multi-layered soil due to pumping from well point are obtained by using the transfer matrix properties and the techniques of the Laplace-Fourier inverse transforms.Numerical results show that the surface settlement of saturated multi-layered soil increases with the increase of time.
