新疆莫莫克水利枢纽工程坝线地质条件比选

Comparison and Selection of Geological Conditions of Dam Line of Momok Water Conservancy Project in Xinjiang

新疆莫莫克水利枢纽工程是提孜那甫河上的控制性工程,起着龙头水库的重要作用,主要承担防洪、灌溉兼顾发电的工程任务。通过对坝址区详细地质勘察,从地形地貌、地层岩性、地质构造等方面对坝线地质条件进行分析,综合对比分析地质条件,两坝线工程地质条件相差不大,上坝线工程地质条件略优于下坝线,因此上坝线为推荐坝线。

Momok Water Conservancy Complex Project in Xinjiang is a control project on the Tizinafu River and plays an important role as the leading reservoir.It mainly undertakes the engineering tasks of flood control,irrigation and power generation.Through detailed geological investigation of dam site area,this paper analyses geological conditions of dam line from the aspects of topography and landform,stratum lithology,geological structure,etc.After comprehensive comparison and analysis of geological conditions,it is found that the engineering geological conditions of the two dam lines are not significantly different,and the engineering geological conditions of the upper dam line are slightly better than those of the lower dam line.Therefore,the upper dam line is recommended.
