摘要
水电工程中的"深埋、大跨、高墙"型水工隧洞应用越来越多,开挖过程中洞室的围岩稳定性问题显得尤为突出。以西南某水电站为例,采用ANSYS软件对地下厂房洞室群分层开挖进行模拟计算。为同类工程及相关研究提供参考。
The stability of adjoining rock is the key point during the excavation in the hydraulic tunnel due to its high require- ment such as high embedded depth, large span, etc. The stepping excavation of cavern groups of underground powerhouse of the hydraulic power station in the southwest China was simulated by ANSYS software, which was provided for the reference for similar engineering.
