利用有限元方法，对桩—承台—土共同作用进行了探讨．采用邓肯张非线性弹性模型，并在桩与土的接触面上设置了ＤａｎｃａｎＣｌｏｕｇｈ 非线性弹性界面模型来模拟两种不同介质接触面形状
The finite element method was used to investigate the joint action of pile-slab and soil. Using the DuncanZhang nonlinear elastic model, a DancanClough nonlinear elastic interface model was set up on the interface between pile and soil to simulate two different media contact surface shapes.
