摘要:: 为更深入认识复杂高层建筑相互作用体系的动力响应特性,结合具体工程背景分别采用罚函数算法和无限单元描述界面接触特性和动力边界,并在此基础上建立大规模深圳老街地铁车站上部结构-地下结构-地基完全相互作用体系三维有限元模型,针对场地土层对基岩输入地震动的影响,对地下连续墙动土压力变化规律以及结构动力响应特性进行了分析,对深圳老街地铁车站结构完全相互作用体系抗震性能进行了评价,可为相关工程设计和具体实践提供参考。

Abstract:: For the aim to investigate the dynamic response of the interaction system of the complicated high-rise building,we described the interface contact characteristics and dynamic boundary by penalty function method and infinite element regarding to specific engineering background.On the basis of it,we established the three dimensional numerical FEM model of the entire interaction system with superstructure-substructure-subsoil of Shenzhen-Laojie subway station.Considering the influence of site soil layer on the inputting ground motion of the bedrock,we analyzed the variation law of soil pressure of the diaphragm wall panel trench and structural dynamic response characteristics,and evaluated the seismic performance of the entire interaction system of Shenzhen-Laojie subway station,which can provide reference to engineering design and practice.
