| 摘 要： | 瀑布沟水电站地下厂房系统洞室群由于地应力高,开挖时围岩变形大,施工中曾多次发生岩爆,对围岩稳定造成了不利影响。通过对施工期围岩变形监测进行分析研究,为地下洞室的开挖、支护及稳定性评价提供了一些可借鉴的经验。

| Abstract: | During excavation of caverns in underground powerhouse complex at Pubugou hydropower station,surrounding rock deformed greatly and rock burst occurred many times during construction due to high in-situ stress,leading to unfavorable effects on surrounding rock stability.Analysis and study are performed for surrounding rock deformation monitoring during construction and analysis results are presented to provide references for excavation,support and stability assessment of underground caverns. |
