| 摘 要： | 以天津市和平路地铁站为例，建立三维计算模型，对软土地区地铁车站与隧道接头结构进行动力时程分析，找出接头部位的应力集中关键点，分析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: | The seismic response of subway station and the tunnel joint structure in soft soil area in Tianjin city were researched by using the finite element analysis software of ANSYS. Taking Heping Road subway station for example, 3 D calculation model was established and time - history analysis was carried out. The focal point of stress on the joint structure was found out and the interaction influ- ence between the tunnel and the station were analyzed. The results show that, firstly, horizontal and vertical direction seismic waves will affect the principal stress of the station and the joint structure. Secondly, horizontal seismic mainly has influence on horizontal displacement in the joint sectional. Vertical seismic dominates the vertical displacement. The earthquake makes the vertical displacement greater than horizontal displacement. |
