摘　　要：尾矿库是矿山的重大危险源,而尾矿坝是组成尾矿库的要素之一,尾矿坝的稳定性状况直接关系着整个尾矿库的安全。该坝址区属中高山河谷地貌,通过对坝址区进行工程勘察,查清了该场地地层构成及工程特性,通过分析钻孔注水试验、压水试验和试坑渗水试验数据,得出了场地水文地质参数,对坝基地基承载力、坝基渗漏及渗漏稳定性进行了评价,并提出坝基渗漏处理方案。The tailings is of major hazards in mines,and tailings dam is one of the elements of the tailings,the stability of the tailings dam condition direct relation with the safety of the tailings.In the dam site belongs to alpine valley landforms,and through the dam site area of engineering survey,found out the site formation structure and engineering properties,through the analysis of borehole water injection test,the water pressure test and trial pit water penetration test data,the field of hydrogeology parameters is obtained,dam foundation seepage and seepage stability of dam foundation bearing capacity,evaluated,and dam foundation leakage treatment scheme is put forward.
