| 摘 要： | 渗流场对于高水压条件下施工期间水下盾构隧道结构及围岩应力场有很大影响.采用有限元方法,通过对江底盾构隧道施工期渗流场单场数值模拟和流固耦合分析,获得施工期渗流场分布特征、围岩位移场分布及衬砌背后孔隙水压分布等,对比分析了双洞同时开工及先后施工的隧道开挖断面周边位移、孔隙水压变化等差异,并提出高水压下隧道地下水排导方式,所得结论可为类似工程的设计施工提供了有益参考及依据.

| Abstract: | Seepage field has a great influence on stress field of shield tunnel structure during construction under high water pressure.The FEM was used to analyze the single filed and coupling seepage field for sub-river shield tunnel.Seepage field distributions,displacements and pore pressure distributions were calculated,and the differences of tunnel border displacement and pore pressure between simultaneous construction and subsequent construction for twin-tubes were comparatively analysis,and groundwater drainsge... |
