【摘要】 基于子结构法对地铁车站-场地-地面建筑相互作用问题进行理论分析,并从运动相互作用和惯性相互作用角度揭示了邻近地面建筑地铁车站地震响应的产生机制;之后利用频域内的数值模拟验证理论分析结果,并系统地探究了各种因素对邻近地面建筑地铁车站地震响应的影响。结果表明:从产生机制上,邻近地面建筑地铁车站的地震响应可以分解为由场地运动引起的运动相互作用和地面建筑振动引起的惯性相互作用;不同因素对运动相互作用和惯性相互作用的影响各不相同,其中地面建筑动力特性和结构间水平间距会影响车站惯性相互作用但不会改变运动相互作用;而场地动力特性和车站覆土厚度对车站运动相互作用和惯性相互作用都有影响。更多还原

【Abstract】 A theoretical analysis on the dynamic interaction of subway station-soil-ground building is carried out based on substructure method,and the mechanism of seismic response of the subway station adjacented to ground building is revealed from the viewpoint of kinematic and inertia interactions.Then,the results obtained in theoretical analysis are verified by the numerical simulation and the effects of different factors on seismic responses of the subway station adjacented to ground building are parametric discussed,systematically.The results demonstrate that:The seismic responses of the subway stations adjacented to ground buildings can be distinguished as the kinematic interaction induced by the field movement and the inertial interaction induced by the vibration of ground building,according to generation mechanism;The influences of various factors on seismic response of the subway station adjacented to ground building are different.The dynamic characteristic of ground building and the horizontal spacing between structures would affect the inertia interaction but would not change the kinematic interaction of subway station.While,the dynamic characteristic of site,the burial depth of subway station have impacts on both interactions of subway station;Finally,due to the existence of inertial interaction.更多还原
