摘　　要：通过水文地质勘察,查清了扎塘赤泥库向牟老泉和百花湖方向的岩溶渗漏通道,根据弥散试验和长期水质监测资料,建立了水动力弥散叠加模型,进行了渗漏污染预测评价。对岩溶渗漏通道采取了垂直帷幕注浆、库内封堵落水洞、赤泥铺盖等综合防渗措施,历时10年,实现了在岩溶发育地区对高浓度碱水进行防渗治理的预定目标,杜绝了扎塘赤泥库废水外排,治理工程取得了显著的效果,保护了岩溶水资源环境。Based on hydrogeological investigation, the karst leakage channels toward Moulao Spring and toward Baihua Lake have been found in Zhatang RedClay Disposal Site. With the application of superposed model of hydrodynamic dispersion, the leakage pollution is predicted and evaluated by means of hydrodynamic dispersion test and longterm groundwater quality monitoring. Integrated control measures, such as vertical grouting curtain of the karst leakage channels, enclosing funnels and paving redclay, have been adopted to reach the goal of preventing leakage of alkaline wastewater with elevated concentration in karst welldeveloped areas for ten years as scheduled. It turns out that these measures have stopped wastewater discharging from Zhatang Redclay Disposal Sites, which produced a remarkable leakproof effect and protected the environment of karst water resources for ten years.
