摘要
探讨了水工隧洞设计施工中有关洞室支护与衬砌、防水与排水设计的问题。根据工程具体特点和施工水平确定了支护参数;依据隧洞的防渗和排水设计"堵"、"排"原则,确定排水孔深度。实践证明,喷锚支护的岩石固结良好,运行安全。
In this paper, issues on cavern support and lining, waterproof and drainage in design and construction of hydraulic tunnels are demonstrated. Based on specific engineering characteristics and construction level, support parameters are determined. According to principles of Blocking and Drainage of impermeability and drainage design of the hydranlie tunnels, depth of drainage holes is finalized. Practice shows rock mass supported by anchorage with shotcrete is with a good effect in term of consolidation and safety in operation.
