针对羊过水水库岩溶发育的复杂性,采取了多种勘察手段和方法进行岩溶渗漏综合研究。通过分析库区岩溶发育的特征,以及暗河、溶洞、泉水、地下水分水岭的分布情况及其与库水的补排关系,指出西河虽属排泄性河谷,但蓄水后库区左岸部分地段地下水分水岭低于正常蓄水位,并存在一段长680m、厚25.8m、年渗漏量114.1万m3(占总库容的3.64%)的透水带。最后得出羊过水水库虽部分地段存在溶隙性渗漏,但总体蓄水条件较好的结论。
Aiming at the complexity of karst development in Yangguishui Reservoir, a variety of survey methods and methods were taken to comprehensively study the karst leakage. By analyzing the characteristics of karst development in the reservoir area and the distribution of underground rivers, caves, springs and groundwater watersheds and their relationship with the reservoir water supply, it is pointed out that although the West River is a draining river valley, the groundwater in the left bank of the reservoir area The watershed is lower than the normal water level, and there is a section of permeable belt 680m long and 25.8m thick, with an annual leakage of 1,141,000 m3 (3.64% of the total storage capacity). Finally, the conclusion is drawn that although some reservoirs in Yangshui Reservoir exist the seepage-induced leakage, the overall water storage conditions are better.
