湖北省麻城市浮桥河水库位于湖北省麻城市境内、长江支流举水一级支流浮桥河上 ,控制流域面积 3 81km2 ,总库容 5 .3 95亿m3。是一座以防洪、灌溉为主 ,兼有城镇供水、工业供水、发电、养殖、航运及旅游等综合效益的大 (Ⅱ )型水库。浮桥河水库工程于 195 9年 12月开工 ,1960年 7月大坝基本建成。大坝为粘土心墙组合坝 ,坝高 2 9.7m ,坝顶长 2 60m。浮桥河水库大坝存在的主要工程地质问题有 :坝基、坝肩渗漏问题 ;坝基渗透稳定问题和白蚁危害。水库大坝已被鉴定为“三类坝” ,属于病险水库。对大坝险情及防渗加固处理方案作了详细介绍。
The floating bridge river reservoir in Macheng City, Hubei Province, is located in Ma City, Hubei Province. The tributary of the Yangtze River is a waterfront tributary of the Fuqiao River with a controlled drainage area of 3 81 km2 and a total storage capacity of 539 million m3. It is a large (Ⅱ) reservoir that is mainly flood control and irrigation, and has the comprehensive benefits of urban water supply, industrial water supply, power generation, breeding, shipping and tourism. The pontoon river reservoir project started in December 1959, and the dam was basically completed in July 1960. The dam is a clay core wall composite dam with a height of 2 9.7m and a crest length of 2 60m. The main engineering geological problems in the pontoon dam are as follows: the dam foundation, the seepage of dam abutment, the stability of dam foundation infiltration and the termite damage. Reservoir dam has been identified as “three types of dam”, belonging to the reservoir. Da Dan danger and seepage control measures made a detailed introduction.
