尾矿库区碎石土边坡稳定性及加固分析

Analysis on the Stability and Reinforcement of Gravel Soil Slope in Tailings Pond Area

针对尾矿库区碎石土边坡的特殊性质,文章采用先进的数值模拟方法,结合摩尔-库伦屈服准则对边坡的稳定性进行了综合评估。通过对比不同桩型(A型桩和B型桩)及桩位组合,发现桩位的变化对边坡稳定性系数具有显著影响。特别是A型桩的桩位变化引起的边坡稳定性系数变化范围较大,这表明A型桩在加固碎石土边坡方面具有较高的敏感性。因此,在实际工程中,应优先考虑将A型桩布设于关键位置,以最大限度地提高边坡的稳定性。

In view of the special properties of the gravel soil slope in the tailings pond area,this paper adopts the advanced numerical simulation method and combines the Mohr-Coulomb yield criteria to comprehensively evaluate the stability of the slope.By comparing different pile types(A-type pile and B-type pile)and pile position combinations,it is found that the change of pile position has a significant influence on the slope stability coefficient.In particular,the variation range of slope stability coefficient caused by the change of pile position of A-type pile is large,which indicates that A-type pile has high sensitivity in reinforcing gravel soil slope.Therefore,in practical engineering,priority should be given to the placement of A-type piles in key positions to maximize the stability of the slope.
