建立工作竖井与盾构隧道、明挖隧道相连的空间交叉结构三维模型,采用FLAC3D对该复杂结构进行了纵向地震响应分析,得到了工作竖井与隧道结构连接处关键点的位移和应力响应规律.并通过对地震纵向激励过程中竖井与隧道结构连接处收敛位移和关键点主应力峰值的分析,对该结构的纵向抗震性能做出了评价.
- Abstract:
-
A three-dimensional model of the spatial cross structure connecting the working shaft with shield tunnel and cut-and-cover tunnel was established, and the longitudinal seismic response analysis of the complex structure was analyzed by FLAC3D, and the displacement and stress response laws of the key points at the connection between the working shaft and the tunnel structure were obtained. The longitudinal seismic performance of the structure is evaluated by analyzing the convergence displacement at the junction between the shaft and the tunnel structure during the seismic longitudinal excitation process and the peak of principal stress at key points.
