猫跳河属长江水系乌江南岸的一条支流,全长180余公里,落差549米,平均比降3.05‰,流域面积3,113公里~2。流域上游为丘陵地带,中游由丘陵向山区过渡,下游则是高山峡谷,地形高差达300～400米。流域内年平均气温为13.8℃,年平均雨量为1,300毫米。全河流共分六个梯级开发(见附图),梯级间相互衔接,共利用河流落差384.5米,总装机容量为23.9万千瓦。流域地质构造非常复杂,碳酸盐类岩石占70%以上,岩溶强烈发育,因而构成水库、坝址岩溶渗漏及岩溶对水工建筑物地基稳定影响等一系列复杂问题。针对这种情况,有关设计、施工单位根据河流地形、
The cat jump to the river is a tributary of the Yangtze River water system south bank of the Wujiang River, a total length of 180 kilometers, a drop of 549 meters, the average drop of 3.05 ‰, the basin area of 3,113 km ~ 2. Upper reaches of the basin is a hilly region, the middle reaches of the transition from hills to mountains, the lower reaches of the alpine valley, terrain elevation of 300 to 400 meters. The annual average temperature in the basin is 13.8 ℃ and the annual average rainfall is 1,300 mm. The whole river is divided into six cascade development (see photo), the cascade between the convergence of a total of 384.5 meters of the river, a total installed capacity of 239,000 kilowatts. The geological structure of the basin is very complicated. Carbonate rock accounts for more than 70% and karst develops strongly, thus forming a series of complicated problems such as the seepage of reservoirs and dam sites and the influence of karst on the foundation stability of hydraulic structures. In response to this situation, the design and construction units based on river topography,
