摘要
阻抗长廊式调压室一般规模较大,其作为一种典型的水电站地下建筑物,受地质条件及人工开挖支护方式的影响很大。以黄金坪水电站调压室为例,利用FLAC3D软件对洞室开挖和支护过程中的围岩稳定性进行研究,根据应力和应变的变化情况,提出相应的支护方案并进行模拟分析。结果表明,所提方案合理,可为工程支护设计提供理论依据。
The impedance corridor surge chamber is often large-scale. As a typical hydropower underground structure, it is affected by natural geological conditions and artificial way of excavation and support. Taking Huangjinping surge chamber for an example, FLAC3D is used to study the stability of surrounding rock in the process of excavation and support. According to the changes of the stress and strain, this paper puts forward the corresponding support programs and simulation analysis. The results show that the proposed scheme is reasonable, which can provide a theoretical basis for support design.
