运用FLAC3D对复杂地质与富水条件下大硐室的支护和施工方案进行数值模拟分析,获得大硐室掘进过程中围岩位移与塑性区演化规律,完善和优化了复杂工程与水文地质条件下大断面硐室及过富水断层带巷道支护技术方案与参数。
FLAC3D is used to simulate the supporting and construction of large chamber under complex geology and water-rich conditions. The displacement of surrounding rock and the evolution of plastic zone are obtained during the excavation of large caverns. The complicated engineering and hydrogeological conditions are optimized and optimized Technical scheme and parameters of roadway support in large and large cross - section cavern and water - rich fault zone.
