摘要
鄂北水资源配置工程唐县-尚市输水隧洞单段长16.55km,沿线地质条件复杂,是该输水工程中施工难度最大的明流隧洞项目,隧洞施工过程中易坍塌、强透水、难治理等问题突出。针对该隧洞施工过程中所遇到的技术问题,分别进行了隧洞开挖支护方案设计优化、岩体透水防渗问题控制以及易失稳基坑边坡安全性分析,最终形成了唐县-尚市浅埋长输水隧洞设计施工关键技术体系。相关经验可供类似工程借鉴。
The water conveyance tunnel from Tangxian to Shangshi is the most difficult open-flow tunnel project in North Hubei water resources allocation project. It is 16.55 km long and has complex geological conditions along the route, that the problems of collapse-prone, strong water permeability and difficult harnessing are very outstanding. In view of this technical problems encountered in the construction progress, the optimization of the tunnel excavation and support scheme, the control of water permeability and anti-seepage of the rock mass and the safety analysis of the unstable foundation pit slope were carried out respectively. Finally, the key technology system for design and construction of the shallow-buried long-distance water conveyance tunnel from Tangxian to Shangshi was formed.
