摘　　要：库水在向坝基运移的过程中 ,所产生的水与坝基岩石之间、水与帷幕及混凝土之间的物理化学作用 ,导致形成不同的坝基水质特征。依据多年来的水质分析资料 ,深入地论证纪村大坝坝基水化学特征 ,得出的结论是 :多次工程处理效果明显 ;酸性库水对坝基岩层已不具侵蚀性 。In the transportation process of water seeping in the founation,there exist physic?chemical actions between water and rock of foundation, water and curtain, and water and concrete,which form different characteristics of water quality in the dam foundation. Based on long?term water quality analysis data, chemical properties of water at Jicun Dam foundation was demonstrated deeply. The analyzed results show that the effect of engineering treatment is obvious, the acidic water has no erosive effect on the rock of the foundation;but some measures should be taken to protect the rock from erosion caused by the water in the silt layer in front of the dam and water from the both sides of the earth dam body.
