新疆奇台县某水库工程地质条件与分析

Engineering Geological Conditions and Analysis of Reservoir in Qitai County Xinjiang

从地理位置、基本组成结构等方面介绍新疆奇台县某水库的工程概况,对奇台县某水库开展地质调查工作,分析水库渗漏、水库塌岸、水库浸没和淹没、水库诱发地震等地质问题,并得出结论,为水库的安全运行提供数据支撑。同时综合河道地形地貌、地层岩性、地质构造及其它工程地质条件,将坝址区分为上坝址和下坝址,从地形地貌、淹没损失、河床覆盖层厚度(m)等方面对比分析上下坝址的地质条件。结果表明,下坝线优于上坝线,以期为以后类似工程地质勘察设计提供借鉴参考。

This paper introduces the general situation of reservoir project in Qitai County,Xinjiang from the aspects of geographical location and basic composition structure.Through the geological investigation of reservoir in Qitai County,the geological problems such as reservoir leakage,reservoir bank collapse,reservoir submergence and inundation,reservoir induced earthquake are analyzed,and some conclusions are drawn,which provide data support for the safe operation of the reservoir and integrate the river according to the landform,stratum lithology,geological structure and other engineering geological conditions,the dam site is divided into upper dam site and lower dam site.The geological conditions of upper dam site and lower dam site are compared and analyzed in terms of landform,inundation loss,thickness of riverbed overburden(m),etc.,and it is concluded that the lower dam line is superior to the upper dam line,this study can provide some reference for similar engineering geological survey and design in the future.
