摘要
讨论了系统锚杆的作用机理 ,结合天龙湖地下厂房围岩的各向异性特征 ,运用有限元计算方法模拟其施工开挖过程 ,研究有无系统锚杆支护两种工况下地下厂房主要洞室分期开挖过程中的围岩变位与稳定性 ,计算结果表明系统锚杆对于改善开挖过程中围岩的变形与稳定性具有明显的效果。
The action mechanism of systematic anchors is discussed.In connection with the geological anisotropy of Tianlonghu underground powerstation,3D non linear static and dynamic Finite Element Method(FEM) is used to simulate the excavation process. The surrounding rock's deformation and stability of the main caverns during the stage excavation process in two different conditions, with systematic anchors supported or not, are investigated and compared.The result showes that systematic anchorage during excavation process is effective on the deformation and stability of surrounding rock.
