| 摘 要： | 高地应力下的隧洞开挖过程中，围岩将产生动态的变化。以锦屏二级水电站引水隧洞为例，采用非线性三维有限元法。对其动态开挖过程进行了仿真模拟，分析开挖后的围岩应力分布与变化规律、变形规律与特征以及塑性区范围，为合理设计和施工安全提供依据。

| Abstract: | On the process ot tunnel excavauon in high geo-stress zone , surrounding rocks will have dynamic drift. Taking diversion tunnel in Jinplng Cascade 2 Hydropower Station as an example, the non-linear three-dimensional finite element method is used to simulate the dynamic excavating process and analysze stress distribution, deformation and plastic range of the surrounding rock, which can be the reference to the construction safety and appropriate designing. |
