新疆库尔干水库枢纽布置方案比选分析

Analysis on Comparing and Selecting the Hydroproject Layout Schemes of Korgan Reservoir in Xinjiang

文中从地形地质条件、工程布置、征占地、水力条件、运行管理安全性、冲沙运行效果、施工条件以及工程投资等方面对库尔干水库枢纽布置三个方案进行比选。由于方案一具有布置可行,水力条件好,运行管理安全可靠,冲砂效果好,投资少等优势。因此将方案一作为推荐的枢纽布置方案,即:大坝采用混凝土沥青心墙砂砾石坝,右岸布置溢洪道、泄洪冲沙兼导流洞及发电引水系统。

In this paper,3 hydroproject layout schemes of Korgan Reservoir have been compared from some aspects including topography and geological conditions,project layout,land acquisition,hydraulic conditions,operation and management safety,sediment scouring operation effect,construction conditions and project investmant.Because of having a set of advantages such as feasible layout,good hydraulic conditions,safe and reliable operation management,good effect of sediment scouring and lower investment,the scheme 1 has been selected as the recommended hedroproject layout scheme.This scheme’s contents are as follows.The dam type is asphalt concrete core and sand-gravel dam.At the right bank of the reservoir,a spillway,a flood and sediment scouring and diversion tunnel and a power diversion tunnel are arranged.
