摘　　要：结合某碱渣堆放场的水文地质状况,通过模拟试验,探讨了碱渣堆放场对岩溶地下水的影响。结果表明,碱渣场在冲灰水和大气降水的浸泡、淋滤作用下,其中的氯化物和钙镁盐类大量析出并随碱渣废液一起下渗,石灰岩碎石对氯化物有一定的吸附作用,但能力微弱。据试验数据分析认为,该渣场是焦作市北中部岩溶地下水中氯化物浓度和总硬度持续升高的主要原因。Based on hydrogeologic situation of alkaline residue site,influence of alkaline residue on carst groundwater was discussed by simulating experiments.The results showed that chlorides and solonchak contaning magnesium and calcium,which entered in groundwater with filtering liquid,were separated in the process of soak and leaching under the effect of ash water and precipitation.The absorption effect of limestone to chlorides was limited.According to the experiment data,alkaline residue disposal site was main reasons of growth of chlorides and total hardness in carst groundwater in the north and central section of Jiaozuo,Henan province.
