摘要

以广西省某排泥库为研究区，对该排泥库进行地下水示踪试验，绘制时间浓度曲线，并利用一维水动力弥散模型对试验曲线进行了研究，计算出接收点地下水的流速、弥散系数和弥散度，探讨了示踪试验中出现多峰、双峰现象的机理。试验结果表明，地下水示踪模型计算所得流速与视流速总体接近，对示踪剂投放点和接收点的渗漏途径、地下水的流向、水力联系等情况的分析与实际情况吻合，该方法可以为库外水源污染情况评价和施工提供技术参考。

Abstract

A tailings pond in Guangxi Province was chosen as the study area． Groundwater tracer test was carried out to obtain the time-concentration curves． The velocity of groundwater flow，coefficient of dispersion，and dispersity were obtained by means of the groundwater dispersion model developed using the data from the test． The mechanism of multimodal and double-humped curves was also analyzed． The experimental results show that the calculated flow velocity was in general close to the apparent velocity． The leakage path with the giving and receiving locations of the tracer，the direction of groundwater flow，and hydraulic connection matched well with the observations． The method can provide technical references for future water pollution evaluation and construction of trailings ponds．
