摘　　要：分析了我国病险土石坝渗漏的原因,提出了土石坝渗漏问题的处理原则及其各类防渗处理措施,建议在病险土石坝防渗加固方案比选时,应在可靠性、可行性等安全分析的同时,进行经济对比和施工工效分析。通过优化比选,提出最优的加固模式和加固工法,并结合工程实例,阐述对于一个具体的病险水库大坝,应根据其病害的具体情况,对多种防渗加固方案进行技术、经济和施工可行性的比较,选择技术可靠、经济合理、施工简便的防渗技术方案。The cause of seepage of dangerous earth - rock dam is investigated. The treatment principle and various types of anti - seepage measures are presented. The reliability and feasibility are safety analyzed simultaneously economic contrast and construction efficiency should be analyzed in selecting anti - seepage reinforcement program. By optimizing the selection, the best reinforcement pattern and reinforcement method are presented. Combined with engineering project, the technique, economy and construction feasibility of comparison is done for various types of anti - seepage reinforcement projects according to the specific conditions of disease to select the technical reliability, economic rationality, construction simple of anti - seepage technical solutions in the specific dangerous earth rock dam.
