| 摘 要： | 建立了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横向地震响应分析,得到了工作竖井与隧道连接处支护结构关键点的位移和应力响应规律。通过对地震横向激励过程中竖井与隧道连接处支护结构收敛位移和关键点主应力峰值的分析,对该结构的横向抗震性能做出了评价。

| Abstract: | Three dimensional model of spatial crossing structure by which working shaft is connected with shield-driven tunnel and open cut tunnel was established.Transverse seismic response analysis of the complicated structure was done by use of FLAC3D.Displacement and stress response rule of key point in the supporting structure of joint between working shaft and tunnel was gained.Convergence displacement of the supporting structure of joint between working shaft and tunnel,principal stress of key point were analyz... |
