| 摘 要： | 采用三维弹塑性有限元计算,对某水电站地下厂房开挖过程进行了数值模拟,分析了开挖过程中毛洞周边围岩位移和应力的变化规律,分析结果表明厂房由于洞室围岩比较破碎,围岩开挖变形量较大,洞室的稳定性较差,开挖后要及时施工支护结构。

| Abstract: | The excavation process of an underground power plant was simulated by using three-dimensional elastic-plastic finite element method.The changes of the displacement and stress of the surrounding rock around the cave is analyzed.The calculation and analysis result show that the stability of the cave is poor and the rock excavation deformation is larger as the surrounding rock is much more broken,the supporting structure should be constructed in time. |
