斜坡桩土共同作用的接触分析

Slope Pile-soil Interaction of Contact Analysis

以Ansys软件为平台,建立一种桩-土共同作用的三维非线性有限元模型,研究坡体上的桩水平位移及剪应力变化情况,充分考虑材料和桩土交界面的非线性影响因素。通过改变土体参数的大小定性描述土体的粘聚力、内摩擦角对斜坡体上的桩位移及剪应力的影响,分别取桩的底部、中部、顶部参数值描绘桩身的水平位移及剪应力随着土体参数的变化趋势,为实际工程提供参考价值。

With Ansys software platform,establishing a kind of pile and soil interaction of 3d nonlinear finite element model,analyzing piles on slope body in level direction of displacement and stress change,fully considering nonlinear factors of materials and pile-soil interface.By changing the size of the soil parameters,qualitative description of soil stick together force,internal friction angle of slope pile effect on sress and displacement,are taken at the bottom of the pile,middle and top parameter value representing pile body level direction stress and displacement with soil parameters for practical engineering change trend,provide a reference value.
