| 摘 要： | 针对黑岱沟露天矿排土场西部变形区无法在该区继续进行后续排弃工作的问题,通过对影响变形区边坡稳定的基底、水、排弃物等主要因素进行分析,得出积水入渗是导致变形区排土场边坡稳定性下降的主要因素。进一步分析了变形区边坡变形破坏的主要模式,结果表明:坡角置换与压脚的设计是边坡控制的关键,结合数值模拟计算结果,提出了对排土场西部变形区坡脚进行土岩置换及填方压脚的治理措施。

| Abstract: | In view of the problem that Heidaigou open-pit mine dump western deformation area cannot go on dumping,the main factors affected slope stability are analyzed such as basement,water,the dump,Laws of water infiltration is regarded as one of the main factor affected slope stability,And main failure modes are further analyzed in deformation area,and the results show that: the slope Angle replacement and presser foot design is the main factors to control the slope with numerical simulation.At the same time treat... |
