摘要
为了研究车辆荷载作用下露天矿道路边坡稳定性,对露天矿道路及车辆特点进行总结,基于极限平衡法推导出车辆荷载作用下的露天矿道路边坡稳定性分析方法,并对安家岭露天矿运输道路进行分析。研究结果表明:端帮道路边坡稳定系数为1.042,内排土场运输道路稳定系数为1.120,中间桥的稳定系数为1.173。将端帮路边坡角降低至70°时,稳定系数提高至1.120,中间桥宽度增大至40 m以上时,稳定性可提高至1.20以上,可满足运输安全要求。
In order to study the road slope stability under the vehicle load,the characteristics of road and vehicle in openpit mine were summarized.Based on the limit equilibrium method,the analysis method of road slope stability under vehicle load was deduced,and was applied on Anjialing Openpit Mine.The results showed that the stability coefficient was respectively 1.042 for end-slope road,1.120 for inner dump road and 1.173 for middle bridge road.When the angle of end-slope was decreased to 70°,the stability coefficient would increase to 1.120,and when the width of middle bridge was increased to more than 40 m,the stability could be improved greater than 1.20,which could guarantee the safety of transportation requirement.
