【摘要】 该文以云南德厚水库建设工程为例,针对罗世鲊村-黑莫村一带分布有地下水位低槽区,水库蓄水后存在渗漏问题,在分析库区地质资料及水文地质资料的基础上,结合实地踏勘,确定潜在的渗漏通道。采用示踪试验,在地下水位低槽区的ZK15和ZK02钻孔处,进行食盐和孢子粉示踪剂的投放,并在盘龙河畔的天然泉水出露点S1和S2处监测。示踪试验结果表明,地下水位低槽区与泉水S1和S2存在水力联系,并用示踪剂估算岩溶地下水的实际流速约为620m/d。更多还原

【Abstract】 In this paper,taking the construction project of Dehou reservoir in Yunnan for example,aimed at the underground water trough area in the area from Luoshizha village to Heimo village,the seepage problem will appear after water impoundment.Based on analyzing the geological and hydrogeological data about reservoir area,combined with reconnaissancd in fields,the potential seepage channel is determined.Using the tracer experiment,the tracer like salt and GLS are thrown in ZK15 and ZK02 in underground water trough area.And they are monitored in the natural spring water dew points S1 and S2 at the Panlong riverside.The results of tracer experiment show that the underground water trough area has hydraulic connection with spring water at S1 and S2,and the actual flow rate of karst groundwater is estimated about 620m/d by tracer.更多还原
