清华洞水库工程混凝土堵洞体布置及结构型式分析

Analysis on layout and structure pattern of concrete cave-plug for construction of Qinghuadong Reservoir

根据当地工程地质条件,清华洞水库的建设因地制宜地利用盲谷进行堵洞蓄水成库,采用H型混凝土堵洞体作为水库的挡水建筑物,打破了常规的大坝型式,具有结构可靠、工程量小的优点。混凝土堵洞体在清华洞水库工程应用中技术上的成功和较好的经济效益,对在岩溶地区兴建类似的水利工程具有一定指导意义。

Based on the local engineering geological condition, Qinghuadong Reservoir is constructed according to the local con- dition with utilization of blind valleys therein by plugging karst caves to form a reservoir for water storage, i. e. taking a concrete cave-plug of H type as the water retaining structure of the reservoir, which takes breaks up the normal way to construction reser- voir with water dam and has the merits of reliable structure and less construction quantity. With technical success and better eco- nomic benefit, the application of the concrete cave-plug to the construction Qinghuadong Reservoir has a certain guiding signifi- cance to the construction of the similar water works within a karst region.
