乌江渡水电站位于乌江中游,地处贵阳遵义之间,电站装机容量63万千瓦,年发电量33.4亿度,是我国在岩溶地区兴建的一座大型水电站。坝址位于倒转背斜一翼,岸坡陡峭,河床窄狭,枯水季水面宽度仅70米。坝基座落于总厚度为233米的下三迭统石灰岩上,其上下游均为页岩组。岩层走向与河流方向近于垂直,倾向上游,倾角60°～65°。两岸岩溶发育,断裂密集。坝肩附近洞穴总体积达8万多米~3,左岸部分地段沿
Located in the middle reaches of the Wujiang River, Wujiangdu Hydropower Station is located between Zunyi and Guiyang. The installed capacity of the hydropower station is 630,000 kilowatts and annual generating capacity is 3.34 billion kilowatts. It is a large hydropower station built in karst areas in China. The dam site is located on the reverse anticlinal wing, steep bank, narrow narrow riverbed, dry season, the water surface width of only 70 meters. The foundation of the dam is located on the Lower Triassic limestone with a total thickness of 233 meters. Both the upper and lower reaches are shale formations. The strike of the strata is close to vertical with the direction of the river, with an inclination of 60 ° ~ 65 °. Both sides of the karst development, intensive fracture. The total volume of the cave near the dam abutment is more than 80,000 m ~ 3, along the left part of the lot
