| 摘 要： | 利用ANSYS有限元分析软件，研究天津软土地区地铁车站与隧道接头结构的地震响应。以和平路地铁站为例建立了三维计算模型，对其进行动力时程分析，找出接头部位的应力集中关键点，从而分析了隧道与车站之间的相互作用影响。研究表明:水平方向和竖直方向地震波都会改变车站与隧道接头结构的主应力大小；在接头截面上，水平方向变形主要由水平地震作用控制，竖直方向变形主要由竖直地震作用控制，地震导致的竖向变形大于横向变形。

| Abstract: | Using the finite element analysis software of ANSYS, researching the seismic response of subway station and the tunnel joint structure in soft soil area of tianjin. According HePingLu subway station, establish 3 D calculation model and make time-history analysis. Find out focal point of stress on the joint structure .Analysis the interaction influence between the tunnel and the station. Research shows: First, horizontal and vertical direction seismic waves will affect the principal stress of the station and the joint structure. Second, Horizontal seismic main influence of horizontal displacement in the joint sectional. Vertical seismic decided vertical displacement. The earthquake makes the vertical displacement greater than horizontal displacement. |
