| 摘 要： | 以"板-梁-柱"双层隧道内部结构体系为例,通过数值模拟的手段研究了双层车行结构与盾构管片连接形式,其中包括:固接、铰接、链杆连接、无连接4种连接方式。研究结果表明,4种连接形式的抗震性能差异较小,链杆连接形式较无连接形式内力小,同时满足强度与变形要求。

| Abstract: | Taking the internal structural system of"plate-beam-column"double-layer tunnel as an example,the connection form of double-layer vehicle structure and shield segment is studied by means of numerical simulation including four connection modes of fixed connection,hinged connection,chain link connection and no connection.The results show that the seismic performances of four connection forms are less different.The internal force of the chain link connection form is smaller than that of the no-connection form,and meets the requirements of strength and deformation at the same time. |
