摘要
隧道工程项目受工程地质条件、水文地质条件及人为因素等影响,导致山体滑坡现象偶有出现。本文结合云南省香格里拉至丽江高速公路洼里别隧道项目,应用Midas GTS NX建立三维地质模型,导入FLAC3D软件进行模拟计算,对该隧道开挖过程中的滑坡的位移和隧道结构的位移进行分析,得到相应的变化规律。本文的分析研究,为加固治理提供了理论支持,同时为今后类似工程提供参考和借鉴。
Affected by engineering geological conditions,hydrogeological conditions and human factors,tunneling project is prone to occasional mountain landslide.Combined with the Shangri-La-Lijiang Expressway Walibie Tunnel in Yunnan Province,Midas GTS NX was used to establish a three-dimensional geological model,and then it was input into FLAC3D software for simulation calculation.The displacements of the landslide and tunnel structure during the tunnel excavation process were analyzed,and the corresponding change rules were obtained.The analysis and research in this paper provide theoretical support for reinforcement and governance,and at the same time provides reference for similar projects in the future.
