摘要
针对废渣场的废渣材料软硬比例发生了不利于堆放边坡稳定的特殊情况,应用极限平衡法、数值模拟及数值微分对渣场稳定进行分析计算。根据计算结果,通过改变堆放结构,设计出了安全可行的废渣排弃方案,并通过现场实验对排弃方案进行了验证。结果表明,设计方案能够保证渣场运行的安全、稳定,并得出了可供借鉴的结论。
The variation of ratio between soft and hard slag materials in a slag dump has an adverse effect on the dump’s slope stability.This paper presents a study on modeling the stability of dump slope using the techniques of limit equilibrium,numerical simulation,and numerical differentiation.Based on the calculation and modeling,a safe feasible plan for dumping slag is obtained by modifying the stacking structure of the slope.The plan is tested in field experiments and the result shows that the design can warrant the dump’s safety and stability.
