摘要
通过FLAC3D软件模拟了深部软岩近距离巷道垂距及掘进过程对巷道围岩变形的影响,主要模拟研究不同垂距巷道开挖时邻近巷道围岩的变形情况,总结了不同垂距及不同掘进过程与巷道围岩位移的关系,得出了深部软岩近距离巷道布置的合理垂距及不同掘进过程时巷道围岩的变形规律。
Simulates the influence of vertical distance of short-distance roadways in deep soft rock and the process of excavation has on surrounding rock deformation by FLAC3 Dsoftware, mainly simulates the deformation of surrounding rock in adjacent roadway when excavating in different vertical distance roadways. Summarizes the relationship of the different vertical distance as well as different process of excavation and the displacement of surrounding rock of roadway. Then, obtaining the reasonable vertical distance of short-distance roadways in deep soft rock and some regular pattern about the deformation of surrounding rock under the influence of different process of excavation.
