王瑶水库位于延安市以上延河支流杏子河中游,距延安市65公里,总库容2.03亿立方米,水库任务以防洪为主,兼有灌溉、发电等综合效益。大坝为均质土坝,最大坝高55米。自1972年大坝建成以米,坝体曾不断发生裂缝,影响水库的安全运用,被列为全国重点病险水库之一。为了搞清王瑶水库的病害,拟定处理措施,从1986年起,南京水利科学研究院、水利部水利大坝安全监测中心、水利部西北、陕西省水利科学研究所以及省内设计、施工、管理等单位,进行了大量的资料整理、试验研究和分析工作,提出了14份安全论证文件。在此基础上,陕西省水利水土保持厅
Wangyao Reservoir is located in the middle reaches of Xingzi River, a tributary of Yanhe River above Yan’an City. It is 65 km away from Yan’an City with a total capacity of 203 million cubic meters. The reservoir task is mainly flood control with the combined benefits of irrigation and power generation. Dam is a homogeneous earth dam, the maximum dam 55 meters high. Since 1972, the dam was built in meters, the dam body has been a continuous crack, affecting the safe use of reservoirs, was listed as one of the national key reservoirs. In order to understand the disease of Wangyao Reservoir and formulate treatment measures, from 1986, Nanjing Water Conservancy Research Institute, Ministry of Water Conservancy Dam Safety Monitoring Center, Ministry of Water Resources, Northwest, Shaanxi Provincial Institute of Water Resources and the province’s design, construction, Management and other units, conducted a lot of data collation, experimental research and analysis, put forward 14 safety demonstration documents. On this basis, Shaanxi Provincial Department of Water Conservancy and Soil Conservation
