露天矿复合边坡的力学特征及变形规律

Mechanical characteristics and deformation law of composite slope in open-pit mine

对哈尔乌素露天矿复合边坡形成过程中的应力和位移规律进行研究,得到了开挖过程中边坡临空面的位移量随深度增加而增大,堆载过程中岩体沉降位移随排土场中心距离的增大而减小,开挖堆载联合作用下工程区域内的地表位移起伏波动变化的结论。

The article researches the stress and displacement law in the process of composite slope form in Harwusu Open-pit Mine, and obtains the conclusion that the displacement of slope surface increases with depth increasing in excavation process; the subsidence displacement decreases with the dump center distance increasing in stack process; under the effect of excavation and stack, the surface displacement changes in engineering area.
