摘要:
目前地铁车站设计中地连墙与车站主体结构之间常采用复合墙与叠合墙两种连接方式,本文基于有限元方法,针对不同连接方式导致结构地震反应差异的问题,采用ABAQUS建立了土-地下连续墙-地铁车站静动力耦合有限元分析模型,分析了地连墙与主体结构连接方式对地铁车站层间位移角、侧移位移反应、动态损伤演化规律等结构地震反应的影响。研究表明:叠合墙地铁车站相对复合墙车站地震损伤整体上显著降低,且具有更好的抗侧移刚度,两种连接方式改变结构的薄弱位置,但两种连接方式中板的中间跨两端都是薄弱位置,应给予足够的重视。
Abstract:
At present, in the design of a subway station, two types of connection methods, compound wall and composite wall, are often used to connect the diaphragm wall to the station. In this paper, we study the difference in structural seismic response caused by different connection methods based on finite element method. ABAQUS is used to establish a static-dynamic coupling finite element model for soil-diaphragm wall-subway station. The influence of the connection method between the diaphragm wall and the station on the seismic response of the structure such as the interlayer displacement angles of the subway station, the lateral displacement response, and the dynamic damage evolution rule were analyzed. The results indicate that, the composite wall station suffers less damage than compound wall station during seismic load, and it has better lateral stiffness. The two connection methods change the weak position of the structure, but the ends of the middle span of the middle plate in both connection modes is a weak position and should be given sufficient attention.
