摘要
运用FLAC3D有限差分软件,结合关角隧道工程,建立了两种隧道防排水模型,基于流固耦合理论分析了隧道周围渗流场的演变规律,得出水位降值随着Q边界/Q衬砌值的增大而减小,当Q边界/Q衬砌=0.01时,水位降值最大,为1.1 m。全排水和限量排水两种模型的稳定水位降值分别在0.76 m^0.86 m和0.27 m^0.45 m之间。
By applying the FLAC3D software and combining with the Guanjiao tunnel, the undrained models of double tunnel are established. E- volution laws of the seepage field around the tunnel have also been analyzed based on the Fluid-Mechanical Interaction theory, drainage and limit the entire drainage model year changes in water level reached in the whole model for the different value of Qboundary/Qlining of the value of drawdown. As the water level drop border/lining of the increased value, reduced the water level drop, when Qboundary/Qlining = 0.01 when the water level dropped the most, the value of drawdown is 1. 1 m. Limited-wide drainage and drainage stability of the two models for the water level dropped 0.76 m - 0. 86 m, respectively, and between 0.27 m -0. 45 m.
