1 概况甘泽坡水利枢纽位于黄河中游晋、陕黄土高原峡谷段末端,下距禹门口约2km,上距壶口瀑布约60km。左岸属山西省河津市,右岸属陕西省韩城市。其开发任务为灌溉供水和径流发电。最大坝高104m,坝顶长度449m,总库容5.84亿m~3,总装机容量440MW。2岩溶发育规律2.1 岩溶形态坝区内发育在奥淘系灰岩中的岩溶,按其发育年代,可分为古岩溶和近代岩溶。古岩溶主要受加里东期运动影响而产生,岩溶形态多分呈漏斗状及囊状,但均被后期沉积的铝土页岩和山西式铁矿等所充填,且结合
1 Overview Ganzepo water conservancy hub is located in the middle reaches of the Yellow River in Shanxi, Shaanxi Loess Plateau canyon section of the end, about 2km away from the Yu door, about 60km away from the Hukou Waterfall. The left bank belongs to Hejin City, Shanxi Province, and the right bank belongs to Hancheng City, Shaanxi Province. Its development mission is irrigation and water supply and runoff power generation. The maximum dam height is 104m, the crest length is 449m, the total storage capacity is 584 million m ~ 3, with a total installed capacity of 440MW. 2 Karst development 2.1 Karst morphology Dam zone developed in the Ordovician limestone karst, according to their age, can be divided into ancient karst and modern karst. Paleokarst is mainly caused by the Caledonian movement. Karst fractures are funnel-shaped and cystic, but they are both filled by later-deposited alluvial shale and Shanxi-style iron ore.
