石城子二级电站引水系统优化设计研究

The study for the optimization design in Shicheng second sub-power station diversion system

石城子二级电站为山区引水式电站,引水系统线路长,地形、地质情况复杂,本文经过充分论证,对引水系统的选线、形式、引水建筑物布置及结构形式进行了优化设计,推荐方案取消了渡槽等跨沟建筑物,降低了施工难度,节省了投资,缩短了施工工期,同时又增加了电量,取得了良好的社会效益和经济效益。

Shicheng second sub-power station is a mountain diversion power plant,which has the long lines of the water diversion system,complex terrain and geological conditions.This article,after full argument,has carried out optimization design for line selection of the diversion system,form of diversion buildings layout and structures;The recommended plan had canceled the across ditch buildings such as aqueduct,which reduced the difficulty of construction,saving investment,shorten the construction period,while increasing the power,and achieved good social and economic benefits.
