某金矿主厂房区边坡变形破坏分区及治理分析

摘要

During the mining construction process ,stability of artificial stopes in the main plant area is significant-ly influenced by human engineering activities ,for instance,digging,unloading,structures loading and some other fac-tors because of the limitation of the construction plant size .For the solution,firstly the entire slope should be divided to partitions ,and then the stability of the slopes is studied based on their specific geotechnical formation conditions .For the next ,the safety factor of the slope should be calculated using geotechnical software such as Lizheng ,focusing on the safety factor of the sandstone layer variating from intense weathering to completely weathering .By the comparison ,the proper construction scheme can be determined .Finally,considering the computation results ,relevant treatment meas-ures can be confirmed .%在矿山建设中，由于场地条件所限，挖方、卸载和构筑物加载等工程活动显著影响了主厂房区人工坡体的稳定性。根据形成人工边坡的工程地质条件，分区研究了边坡稳定性；应用理正岩土软件，重点计算了强风化、全风化砂岩层边坡的安全系数；通过治理方案对比分析，确定有利于工程稳定性的设计施工方案；综合计算结果，提出了相应的工程处理措施。
