龙滩水电站引水发电系统设计

龙滩水电站地下厂房系统是一个巨型地下洞室群，无论设计、施工还是管理，在国内外都少有先例。电站的引水发电系统的布置是基于拦河大坝采用碾压混凝土重力坝，并在满足首台机组发电工期为６．５年的前提条件下进行的，左岸山体也具备布置大型地下洞室群的条件。尽管引水发电系统的设计仍存在各种困难，但目前的布置在结构布置、围岩稳定、施工、设备安装及运行管理等方面均是可行的。

The system design or Longtan Hydropower Station for diverting water to generate power

The underground powerhouse system of Longtan Hydropower Station is a huge cluster of underground caves.It is rare precedent in domestic and abroad not only for its design and construction but also for its management. The layout of diverting water for power generation is arranged based on adopting RCC gravity dam as its main dam and meeting the prerequisite condition of putting the first generating unit into operation after 6. 5 years of the protect commencement. Meanwhile,the rock body of left abutment also has a condition of deploying a large cluster of underground caves. Although there are still various difficulties in the design of diversion for power generation,the following items of structure layout, surrounding rock stability, construction, equipment installation, operation and management for the present layout are feasible.
