摘要
Abstract
The total length of diversion system in Jisha Hydropower Station is about 15.58 km. The rated head of station is 485.00 m and a penstock supplies water to two turbines. The high-pressure pipeline locates between the surge shaft and powerhouse and consists of a penstock, a bifurcation and two branches. The 1054 m-long penstock is designed to have a maximum internal water head of about 652.2m and is arranged in a way of the combination of horizontal and inclined sections. The exposed and buried penstock arrangements are compared, and different buried penstock schemes are also analyzed from the aspects of structure, economy and construction. Finally, an easy-constructed and economic buried penstock scheme is selected, in which the surrounding rock withstands no force.关键词
