摘要
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.
Three dimensional model of space crossing structure by which working shaft is connected with tunnel shield and open cut tunnel is established.Longitudinal seismic response analysis of the complicated structure is made by FLAC3D.Displacement and stress response rule of Key point in the joint between working shaft and tunnel is gained.Convergence displacement of joint between working shaft and tunnel,principal stress of Key point is analyzed in the process of longitudinal seismic excitation,then longitudinal antiseismic characteristic of the structure is evaluated.
