摘要
本文针对露天矿排土场软土地基滑坡问题,考虑土体的弹塑性性质以及排土工艺对软土地基变形的影响,对本钢歪头山铁矿排土场软土地基进行了弹塑性固结变形分析,得到排土场地基在逐级加载作用下的水平位移,垂直位移和孔隙水压力变化曲线,与实测资料进行对比分析,认为计算结果能够较好地符合实际,可以用于同类型矿山排土场软土地基的破坏变形分析。
The failure of weak foundation of waste dump is a serious problem in open pit mine. In this paper, considering the characteristic of soft soil, the elast-plastic consolidation and deformation analysis of weak foundation of the waste dump in Waitoushan open pit mine has been carried out. The satisfied results, such as pore water pressures, horizontal and vertical displacements during staged construction, are obtained, and the analytical values can explain well the observed data. It can be applied to other mines where similar problems are presented.
