| 摘 要： | 提出研究桩土相互作用的新模式－有限层有限元混合法，将半无限空间问题转化为准二维平面问题求解。经理论分析，推导出可解决弹塑性问题的公式。通过实例分析并与三维有限单元分析比较，证实本方法不仅理论清晰、简捷，而且精度较高，运算速度快，应用前景广阔。

| Abstract: | A new method for pile-soil interaction analysis is proposed to transform a half infinite space problem into a 2-D quasi-plane problem which is more easy to be solved. The theory and formulas of this method are deduced from theoretic analysis. A calculated instance and comparisons with other 3-D FEM methods show that this method is clear, simple and direct in theory,and high in calculation speed and accuracy. It has a better prospect of future application. |
