摘　　要：为查明平果市隆黎赤泥堆场内外岩溶地下水的水力联系,以确定地下水的流向,从而了解未来该堆场的污水污染可能涉及的范围,为此在该堆场区进行了地下水示踪试验。本次试验选择堆场中部有水溶井S20作为投放点,以堆场外围的监测孔及各溶潭饮用水点共21个点作为接收点,采用氯化钠(工业盐)试剂作为示踪材料。试验中,共采取了1014件水样进行了室内Cl-浓度的测定。试验结果表明:研究区地下水的流向局部向东,但总体为东南方向,管道水流速共有快速流、中速流、慢速流等3种;接收点的时浓曲线均为单峰曲线,这显示出从投放点至各接收点之间均只有一条管道。通过示踪试验,本文还定量计算了岩溶管道的几何参数和水力参数。In order to find out the hydraulic connection of karst groundwater inside and outside the Longli red mud storage yard in Pingguo city,to determine the flow direction of groundwater,and to understand the possible scope of sewage pollution in the storage yard in the future,a groundwater tracer test was conducted in the storage yard area.In this test,the water solution well S20 in the middle of the storage yard is selected as the drop point,and a total of 21 points in the monitoring hole and the drinking water point of each solution pool outside the storage yard are used as the receiving point,and sodium chloride(industrial salt)reagent is used as the tracer material.In the test,a total of 1014 water samples were taken for the determination of indoor Cl~-concentration.The test results show that the flow direction of groundwater in the study area is partial to the east,but generally to the southeast.There are three types of flow velocity in the pipeline:fast flow,medium flow and slow flow;The time-concentration curve of the receiving point is a single-peak curve,which shows that there is only one pipeline from the delivery point to each receiving point.Through the tracer test,the paper also quantitatively calculates the geometric parameters and hydraulic parameters of the karst pipeline.
