针对坐落于软岩地基上的水电站厂房地基摩擦桩加固措施,采用ANSYS中的面—面接触单元模拟桩—土之间的接触特性,并结合一中等直径灌注桩,分析桩土模型的荷载—桩顶沉降曲线、接触黏聚力—桩侧/端摩阻力和桩径—桩侧/端摩阻力变化关系,总结荷载和参数作用与影响规律,为相似工程的桩土接触数值模拟处理提供参考。
Surface to surface interface element of ANSYS is cited to simulate the contact between pile and soil, and combines with a medium diameter filling pile. The load-settlement curve in the top of the pile, the contactcohesion-contact friction change rule and the pile diameter-contact friction change rule are analyzed. Summarizing the rule, the important information about pile-soil processing and the settlement forecast are provided for the same zone.
