摘要
通过武都引水工程导流洞、紫坪铺工程导流洞和天龙湖引水洞等工程穿越岩溶区、软弱破碎带和堆积体等复杂地质条件下的施工实践,结合针对各工程所进行的现场监测和数值模拟试验,分析了复杂地质条件下的开挖方案和支护措施,在此基础上总结了大断面水工隧洞新奥法施工的经验教训,对不良地质条件下的隧洞建设有一定的借鉴意义。
The economy and reasonable construction under complicated surrounding rocks is the key problem of building larger-span waterpower tunnel. Aiming at the outstanding problem of the geological engineering about Wudou diversion projection, Zipingpu irrigation works and Tianlonghu diversion work, the engineering method of excavating and supporting technique in the soft-crash rock mass is introduced systematically, and the big section excavating schemes in the badness rock mass is also discussed in this paper. Basing the above discussing, the scheme and the principle is given in the end of the paper.
