摘要
对复杂地质条件下的高水头透水衬砌超长水工隧洞进行充排水,目前尚无成熟的标准流程或规范,可供参考的案例也极少,分析总结出相应的技术成果确有必要。以巴基斯坦N-J水电站为例,通过专门分析及总结该电站引水隧洞、尾水隧洞的充排水实施方案、施工组织方式、出现的问题、过程数据等,在隧洞充排水工作的目的、工作内容、过程控制原则、实施方案、风险防控要点、注意事项等方面形成了较为完整的技术成果。研究成果对类似工程具有借鉴意义。
At present,there is no mature standard flow or specification for the filling-drainage of super long hydraulic tunnel with high head permeable lining under complex geological conditions,and there are few cases for reference.It is necessary to analyze and summarize the corresponding technical achievements.Taking the Neelum-Jhelum Hydropower Station in Pakistan as an example,this paper analyzes and summarizes the implementation plan,construction organization,problems and process data for water filling-drainage of diversion tunnel and tailrace tunnel,and then forms a relatively complete technical achievement in the purpose,work content,process control principle,implementation plan,risk prevention and control points,matters needing attention of the tunnel filling and drainage work,which is of great significance for similar projects.
