连续排水边界下成层地基一维固结问题的有限元分析
Finite element analysis of one-dimensional consolidation problem with continuous drainage boundaries in layered ground
摘要
Abstract
Based on the finite element analysis of software ABAQUS, the one-dimensional subroutine of continuous drainage boundaries was developed. Results comparison among the classic Terzaghi's one-dimensional consolidation theory, the analytical solutions of Terzaghi's one-dimensional consolidation equation with continuous drainage boundaries and the analytical solutions of one-dimensional consolidation for a double-layered ground to verify the correctness. According to the layered ground of practical engineering, one-dimensional consolidation problem with continuous drainage boundaries in layered ground was investigated by using changes in different elastic moduli, permeability coefficients and poisson's ratios with the finite element analysis. The results show that continuous drainage boundaries can simulate the practical engineering commendably.关键词
