| 摘 要： | 岩滩水电站扩建工程地下厂房虽岩性坚硬性脆,力学强度较高,但由于其为大跨度、高边墙大型洞室,且发育有F48、f211断裂构造及石英脉,地下厂房区的岩体稳定性特别是不利地质构造的影响不容忽视。文章结合该地下厂房洞室群围岩稳定分析,分别对各部位提出了经济合理的支护措施,也可为其他类似地下工程支护设计提供参考。

| Abstract: | Although the surrounding rock of underground powerhouse chamber for Yantan hydropower station extension project is hard and has great mechanical strength,its stability must be studied due to large span and high side wall as well as unignorable adverse geological effects caused by developed F48 and F211 faults and quartz vein.In this paper,the author puts forward several economical and rational support measures for surrounding rocks of different locations according to the stability analysis,which can be referenced by similar projects. |
