摘要
利用Flac3D有限差分软件渗流模块,基于现场地质钻孔实测渗流参数和地下水位线,建立三维地质渗流数值模型,研究了隧道围岩初始状态下的地下水渗流场分布规律、隧道开挖前后渗流场变化规律以及施工期隧道涌水量,模拟计算结果对裂隙发育、富水地层地下工程防排水设计具有参考意义。
The paper adopts the finite difference software seepage model of Flac3D , establishes the three-dimension geological seepage numeric model based on the measured seepage parameter and underground water line of the site geological drilling, researches the distribution law of the underground water seepage field under the initial status of the tunnel surrounding rock, and indicates the change law for the seepage law before and after the tunnel excavation and the water inflow during the construction, so as to provide some reference for the waterproof and drainage de-sign of the underground projects with cracks and rich stratums by the simulation calculation results.
