摘要
采用FDC-250A型地下水参数测试仪,以放射性同位素131I作为示踪剂,利用单孔稀释法和单孔吸附示踪法分别测定龙口库区地下水的渗透流速和流向,从而推断龙口库区水的渗漏量和渗漏方向,为龙口水库建设防渗提供科学依据。
Taking the radioactive isotope ^131I as the tracer and using FDC-250A type groundwater parameter tester, the filtration velocity and direction of the groundwater in Longkou reservoir area are respectively tested by using the single-bore dilution method and the single-bore absorption tracing method. The groundwater leakage value and the seepage direction are deduced which gives the scientific basis for the construction of the leakage pre- vention of the reservoir.
