摘要
以Biot三维均质饱和多孔介质的固结理论为基础 ,采用相应的变分原理 ,推导了轴对称问题的有限单元法方程。以马来西亚的槟城填海工程为例 ,用有限单元法模拟了软式透水管真空排水固结法处理软土地基的过程。
Based on the 3-D consolidation theory for homogeneous, saturated and poroelastic media by Biot, this paper, employing the corresponding variational principle, develops a finite element method for axisymmetric problems. As an example, procedure of soft-clay foundation reinforcement by means of the vacuum drainage technique for a sea-filling engineering in Malaysia is simulated.
