地下水连通试验的应用比较广泛,但有关地下水连通试验资料整理和分析的论述较少。本文通过地下水连通试验,进行定量分析,根据实际资料整理成示踪剂浓度随时间变化的曲线,利用这个示踪曲线可分析地下水通道展布规律;测算地下河的流量,计算地下过水通道系统的体积。该成果对水工建筑物的渗漏评价,确定地下水来源、去向及边界条件,对地下水污染源的鉴别都具有一定的现实意义,并可为城市给水排水的设计提供依据。尤其对岩溶地区地下水连通试验的资料整理更有实际意义。
Groundwater connectivity test is widely used, but there is little discussion on the compilation and analysis of groundwater connectivity test data. In this paper, groundwater connectivity test, quantitative analysis, according to the actual data collated tracer concentration with time curve, the use of this trace curve can be groundwater channel distribution law; calculation of underground river flow, the calculation of underground water passage system volume of. The results of the seepage assessment of hydraulic structures to determine the source of groundwater, whereabouts and boundary conditions, the identification of groundwater sources have some practical significance, and can provide the basis for the design of urban water supply and drainage. Especially for karst groundwater connectivity test data more practical significance.
