摘要
采用ANSYS结构分析软件建立了三维有限元实体模型,计算了地震作用下桩—土动力相互作用体系的动力反应,分析了体系的加速度反应、位移反应、桩身应变、桩身挠度、桩身弯矩、桩身剪力和桩土间接触压力等,并探讨了桩土刚度比、上部荷载等参数对桩—土相互作用体系的影响。
A three-dimensional finite element solid model is set up by using ANSYS. The dynamic interaction between pile-soil under earthquake is calculated. The seismic responses are discussed includes acceleration response, displacement response, strain response of pile, deflection of pile, bending moment and shear force of pile, contact pressure on the pile-soil interface. The sensibility of parameters influenced pole- soil system, such as rigidity ratio between pile and soil, above load, and so on are discussed.
