摘要
黄金坪水电站地下厂房施工开挖揭示的围岩地质条件好于前期阶段,根据开挖的实际情况,对地下厂房三大洞室围岩支护设计进行了优化,通过施工期围岩稳定监测与反馈分析监测围岩的稳定情况,同时对局部围岩支护设计参数进行了调整。
Geological conditions of surrounding rock in underground powerhouse of Huangjinping hydropower station revealed by excavation are much better than that in early stage. According to the actual circumstance of the excavation,design of excavation and supporting for surrounding rocks is optimized for three main underground caverns. Besides,local surrounding rock supporting design parameters have been adjusted and surrounding rock stability has been monitored according to the analysis of surrounding rock stability monitoring and feedback analysis during the construction.
