【摘要】 蓄能电站地下厂房洞室群埋藏较深、开挖面积较大。在前期的工程地质勘察过程中,各洞室群的布置和轴线设计是否科学合理,成为设计的关键。对此,根据地下厂房及洞室群的地应力测试成果分析,从高程和深度分析原始应力的变化规律、应力场组成情况,并对应力解除和水压致裂两种测试成果进行对比,对施工期发生岩爆的可能性进行分析,从而为优化设计提供必要的参数。更多还原

【Abstract】 Based on the analysis of the in-situ stress measurements of in constructing underground tunnels and chambers of pumped storage power station,this paper presents the results of the regularity of originality stress distribution.By contrasting the productions of stress relief to hydraulic pressure split measurement,this paper also analyzes the rock burst probability in project period so as to provide parameter for optimized design.更多还原
