| 摘 要： | 详细介绍了将修正剑桥模型和Biot固结理论耦合形成的修正剑桥渗流耦合模型二维平面应变有限元方法，采用编制的该模型有限元程序，结合前文介绍的砂井地基三维问题等效成二维问题的方法，对某路堤工程砂井地基的沉降进行有限元计算，得到的计算结果与实测沉降结果比较相近。

| Abstract: | This paper introduces in detail the method of two-dimension FEM program composition based on modified cambridge model coupling biot theory.Adopting the transformation method of axisymmetric vertical drains into plain vertical drains introduced in the former paper,the settlement of one embankment case is computed by FEM,and the computed results show close to the measured ones. |
