摘　　要：本次研究主要根据实测的坝体物理力学参数,对某尾液库进行渗流及稳定性研究,并进行加固改造研究,提出一种斜卧式褥垫排渗体与强湿陷性黄土反坡加固技术,使改造后的尾液库达到超震和千年一遇洪水下二等尾液库的安全使用要求。This study mainly studies the seepage and stability of a tailing reservoir according to the measured physical and mechanical parameters of the dam,and carries out the reinforcement and reconstruction research,and puts forward a reinforcement technology of inclined horizontal mattress seepage drainage body and strong collapsible loess reverse slope,so that the reconstructed tailing reservoir can meet the safe use requirements of second-class tailing reservoir under super earthquake and Millennium flood.
