摘要
以粤湘高速公路水涧山隧道为研究背景,应用FLAC3D有限差分软件,论述了双侧壁导坑法施工对隧道稳定性的影响,并通过对拱顶沉降、水平位移的状态分析,对比了数值模拟结果与实际监测数据,得出了隧道和周边围岩的变化规律。
Taking the Shuijianshan tunnel on Yue-Xiang highway as the research background, the paper applies FLAC3D finite difference soft-ware, discusses the impact of double-side-drift method construction upon tunnel stability, analyzes the arch top subsidence and horizontal dis-placement, compares numerical simulation result to actual monitoring data, and draws the tunnel and surrounding rock changing law.
