摘　　要：压力钢管的直径选择是水电站压力钢管设计的主要内容之一,钢管直径变化使得钢管造价和发电效益同时发生变化。以溪南水电站为例,说明小型引水式水电站可以通过造价增加值收益率来科学合理地选择压力钢管的直径。Diameter selection of pressure steel pipe is one of the main content of pressure steel pipe design of water power station.The change of steel pipe diameter makes steel pipe value and power benefit change at the same time.Take Xinan Hydropower Station as an example that small type hydropower station as a diversion can select reasonably diameter of pressure steel pipe according to the value increment yields.

关 键 词：压力钢管 经济直径 造价 收益 造价增加值收益率
