摘要
考虑地下水 ,地应力及结构面产状和岩溶、剪切带发育的特点修正 ,确定了水布垭水电站地下工程洞室工程岩体质量 ,进行了地下工程的 RMR分类研究 ,讨论了与水布垭地下工程反馈设计及信息法施工的有关问题。
A large Shuibuya hydropower plant will be constructed on the very complicated geological condition. There is a challenge appearing in design and construction of the project. Considering the results of detailed geological exploration, a quality assessment of rock mass for underground buildings of the hydropower plant is carried out. The authors describe the engineering rock mass quality for underground opening as follow: Q und-r=90+3 *R c+250 *K v-100(K 1 +K 2+K 3). The result of RMR for quality assessment of rock mass for underground building of Shuibuya hydropower plant project are illustrated. At last the progressive feedback design and informative construction related to the underground working is presented.
