摘　　要：本次研究主要根据实测的坝体物理力学参数对存在隐患的尾液库大坝进行加固方案研究,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,并对加固后的大坝进行渗流及稳定性研究,并进行加固改造研究。The main focus of this study is to study the reinforcement scheme for the tailings reservoir dam with hidden dangers based on the measured physical and mechanical parameters of the dam body.A inclined horizontal cushion seepage discharge body and strong collapsible loess anti slope reinforcement technology are proposed,and the seepage and stability of the reinforced dam are studied,as well as the reinforcement and renovation research.
