| 摘 要： | 本文根据一种理论模型，利用有限元方法计算考虑渗透作用时地震作用下地基的孔压发展状况，从而分析用挤密砂桩法加固地基抗液化的效果。分析结果说明，在该方法中，砂桩的挤密作用为主要的作用，同时消散作用也能起一定的效果。

| Abstract: | Based on model of sand hole pressure development with consideration on permeation function, this paper researches, by mean of finite element analysis, hole pressure development of the foundation with consideration on permeation function under earthquake condition. Furthermore it analyzes effect of liquefactionproof by using compacting sand pole to solid the foundation. The analysis result shows that compacting status take main role. However dissipating has its effect of liquefaction-proof only under certain condition. |
