Abstract:

Based on Terzaghi’s one-dimensional consolidation theory ,the analytical solution of one-dimensional consolidation of undrained symmetry plane under continuous drainage boundary with self-weight was given. The subroutine of continuous drainage boundary with self-weight was wrote based on the finite element analysis of ABAQUS. Compared with the analytical solution, the results of finite element analysis show that the computing method and the subroutine of continuous drainage boundary are correct. Compared with the condition without self-weight ,The influence factors of undrained symmetry plane with self-weight were researched. At last, the consolidation rate of setting sand layer at different depths in saturated soft clay was analysed by the method of finite element analysis. The results show that most of the time it is more reasonable to set sand layer at the moving range of undrained symmetry plane.
