地震下单桩动力响应的有限元模拟
|
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.
