摘　　要：为满足矿山尾矿坝的渗漏治理,从抗酸稳定性、防渗等级和帷幕完整性三个方面阐述了尾矿坝防渗帷幕的性能要求,基于矿物晶体结构的理论分析和对纯水与酸性渗透液的对比试验,分析了粘土固化浆液的抗酸稳定性,研究了粘土固化注浆帷幕的防渗特性,并结合工程实例,介绍了尾矿坝基础防渗中粘土固化注浆帷幕的设计、施工工艺和质量控制措施。通过对实际工程的质量检查,验证了该防渗技术应用在矿山尾矿坝中的有效性和可靠性。Based on the demands for leakage harness of tailing dam in copper mine, three aspects of acid - resistant reliability, anti - seepage grade and curtain integrality were described to the required characteristics of anti - seepage curtain constructed in tailing dam. Used the combination of the method of theoretic analysis on mineral crystal structural characteristic and the contrast permeability experiments on water and acid solution, the acid - resistant reliability of clay - solidified grouting curtain was analyzed and its anti - seepage characteristics were studied. An actual engineering was presented to introduce the design, the procedure, and the quality controlling measure of clay - solidified grouting. The application in the actual engineering shows the validity and reliability of the curtain.
