摘　　要：为了对元宝山露天矿排土场边坡稳定性作出客观评价,采用相似材料模型实验的方法对排土场进行物理模拟。结果表明:随着排土工作线发展,荷载增加,测点的位移和应力变化特征为:应力趋向负值,出现拉应力,岩体在变形,并且容易破坏,同时位移明显增大。该结论为元宝山露天矿排土场下一步排土方案、边坡监测方案和边坡整治防滑措施的制定提供决策依据。In order to make an objective evaluation of the slope stability of yuanbaoshan Open-pit Mine dump, similar material model experimental method is adopted for dump physical simulation. The results show that, with the development of dump active line and the load increase, the measuring point displacement and stress characteristics are： stress trends to negative value and tensile stress and deformation rock body appears in the rock, and the rock body easily damages, while displacement has notably increased. The conclusion provides basis for decision-making for the next dumping scheme and slope monitoring program and slope anti-slide measures.
