摘　　要： 分析了抚顺西露天矿北帮在水压影响边坡变形特征,对抚顺西露天矿北帮西区W200～W600高陡边坡倾倒滑移变形机理进行了数值模拟分析,并对采取的抗滑桩加固工程和疏干减压工程效果进行了评价,为边坡整治工程设计提供了技术指导和依据。分析结果表明,边坡向斜南翼顺层滑移变形主要集中在第1,2层,采取相应的治理工程之后,边坡变形明显减缓。否则,倾倒滑移体的变形深度将深入到第5层,可能产生沿第5层直到地表的整体滑移。最后介绍了部分治理工程实施后的初步实际效果,希望能够对类似边坡的失稳预测及变形控制研究起到一定的借鉴价值。 By investigating the influence of hydraulic pressure on the deformation of north side slope of Fushun open cast, the slide and inclination deformation mechanism of high steep slope in the area W200-W600 are presented, as well as the evaluation of effect of reinforcement for anti-slide pile and dewatering. The results show that most of the maximum deformation appears in layers No.1 and No.2, and the deformation decreases greatly after being reinforced. Otherwise, the slide depth will get into layer No.5 and this will lead to the slide of the whole layer No.5. Finally, some practice effects are introduced and it can provide references to the prediction and control of failure and instability of the similar slopes.
