| 摘 要： | 提出了平面应变条件下复合地基沉降计算的复合本构有限元法。根据桩土界面处力的平衡条件和竖向变形协调条件，由桩、土材料各自的本构方程形成复合地基的本构方程，桩和桩周土可以采用任意非线性本构模型。工程实例分析表明，所建议的方法是有效的。

| Abstract: | In this paper, finite element method for the settlement of composite ground based on composite constitutive law is proPOsed on condition of plane strain. The composite constitutive law of composite ground is obtained by means of equilibrium and compatibility at the interface between pile and soil around the pile.The constitutive model of pile and soil may be nonlinear. The proPOsed method is verified with a practical settlement calculation of soft roadbed improved by flyash-lime-soil piles. |
