清渡河水库工程位于贵州省铜仁市印江自治县境内的乌江右岸一级支流清渡河上,工程区属中山~低山地貌。坝址区左坝肩基岩裸露,坡度较陡,右坝肩边坡坡度一般为28~30°,倾向左岸偏下游,边坡为斜顺向坡,岩层倾角略大于坡度。水库工程布置由沥青混凝土心墙坝、溢洪道和引水钢管组成,溢洪道布置于右坝肩,采用侧槽式溢洪道,由于边坡为顺向坡,需考虑溢洪道边坡稳定问题。
The Qingduhe reservoir project is located on the Qingdu River, a tributary of the right bank of the Wujiang River in the Tongyin Autonomous County, Tongren City, Guizhou Province. The project area belongs to the Zhongshan-Hilly landscape. The basement rock of the dam abutment at the dam site is bare with a steep slope. The slope of the right abutment slope is generally 28-30 °, with a tendency of leaning to the left bank and the slope is inclined to the slope. The inclination of the rock formation is slightly larger than the slope. The reservoir layout is composed of asphalt concrete core dam, spillway and water diversion pipe. The spillway is arranged on the right abutment dam. The side channel spillway is adopted. Because the slope is forward slope, the slope stability of the spillway should be considered.
