摘要: 为判断索风营水电站右岸地下厂房洞室群围岩稳定性,采用自主研制的三维弹塑性有限元程序对该地下厂房洞室群岩体初始应力场、开挖方案、开挖过程、加固措施、围岩应力及变形等方面进行了数值模拟。数值模拟结果表明,该地下厂房洞室群围岩稳定性整体较好,可为工程设计与施工提供指导。

Abstract:  In order to estimate the stability of the surrounding rock for cavern group of underground powerhouse at right bank of Suofengying Hydropower Station, the numerical simulation of the initial stress field , the excavating scheme, the excavating process, reinforced measures, stress and deformation of the surrounding for the underground cavern group are carried out by adopting a self-developed 3D Elastoplastic FEM program. The results of numerical simulation indicate that the stability of the underground cavern group is good enough to meet the requirement of engineering design and provide the guidance for engineering design and construction.

Key words: Suofengying Hydropower Station  ,   cavern group of underground powerhouse  ,   stability of surrounding rock  ,  numerical simulation
