摘要
岩溶渗漏是在碳酸岩分布区修建水利工程经常遇到和必须解决的重大问题。为研究黄河龙口水利枢纽库区的地下岩溶发育和渗漏情况,以亚硝酸钠为示踪剂,采用微量化学示踪方法在库区进行了示踪试验,并结合相关地质勘察资料对试验结果进行了分析。结果表明:试验区内投源孔ZK110到下游6000m的范围内,地下岩溶裂隙存在较好的连通性,连通程度和连通形式十分复杂,岩体的渗透性极不均一。地下水流总体流向为由北向南。
Karst seepage is a big problem when building conservancy facilities in the karst area. In order to study the underground karst development and seepage in the area of Longkou conservancy facilities on the Yellow River, microchemical tracing test was conducted using the tracer of sodium nitrite. The testing result and the geological investigation data revealed: 1)Karst and cranny were well developed and connected in the range of bore hole ZK110; and 2)The general flow direction of groundwater is from north to south.
