万家寨水电站浅埋式引水压力钢管设计

Design of diversion slightlyembededpenstocks for the Wanjiazhai Hydropower Station

万家寨水利枢纽工程电站引水压力钢管的设计采用浅埋式软垫层压力管道结构型式，设计包括强度设计、连接设计和垫层设计。既保证按时发电，又节省投资，效益显著。为今后水电站压力管道的合理布置和结构设计提供了新的思路。

The penstocks of the Wangjiazhai Hydropower Station are designed as slightlyembededdam penstocks with soft cusion layerA method is proposed on strength calculation,joined design and cushion layer designThis will not only guarantee a schecluled generation but also save cost,gaining an obvious benefitThis design provides a new concept for the rational arrangement and structural design of the penstocks for other hydropower stations
