1 工作概况陡坡水库位于镇平县境内,是唐白河水系潦河支流上一座中型水库,兴利目标以防洪灌溉为主,兼顾水产养殖,水库总库容4940万m~3。水库工程主要建筑物等级为3级。2001年水利部大坝安全管理中心鉴定大坝为3类坝。水库大坝坝型为粘土心墙坝,坝顶高程202.1m,最大坝高21.789m,坝顶长758m,坝顶宽5m,迎水坡坡比为1:2.5、1:3、1:4,背水坡坡比为1:2、1:2.5、1:3,坝基防渗型式为粘土铺盖,下游坝脚排水采用贴坡排水。
1 Work profile Steep slope reservoir is located in Zhenping County, is a tributary of the Tangbai River Liaohe River on a medium-sized reservoirs, Xingli target mainly flood control, taking into account aquaculture, the total reservoir capacity of 49.4 million m 3. Reservoir main building level 3. In 2001, the Ministry of Water Resources Dam Safety Management Center identified three types of dams. The dam type of the dam is clay core wall dam, with a crest elevation of 202.1m, a maximum dam height of 21.789m, a crest length of 758m, a crest width of 5m and slope ratios of 1: 2.5, 1: 3 and 1: 4 , The slope ratio of back slope is 1: 2, 1: 2.5 and 1: 3. The impervious seepage type of dam foundation is covered with clay and the drainage of downstream dam foot adopts slope drainage.
