摘要 比较弓长岭矿业公司汽运六队排土场边坡工程与已有边坡在岩性、结构、自然环境、变形主导因素和发育阶段等方面的相似性,确定了排土场散体、半压实体、压实体及基岩的物理力学参数,并运用FLAC3D对排土场边坡的稳定性进行模拟分析,对比Bishop法和Janbu法及FLAC3D计算的边坡稳定性系数.结果表明:排土场一台阶边坡极不稳定,潜在滑移带在距离边坡边缘约13 m处;二台阶边坡稳定性较好,计算极限堆载高度为108 m,达到极限堆载高度时,存在安全隐患,需采取加固措施. The similarity between the spoilbank operated by the sixth truck team in Gongchangling Mining Company and other existing spoilbanks was compared in terms of lithology,structure,natural environment,dominant factor of deformation and developmental stages.The physical and mechanical parameters of granular media,half-compaction body,compaction body and bedrock in waste pile were determined.FLAC3D was used to simulate and analyze the slope stability of spoilbank,and it was compared with the slope stability coefficient obtained by Bishop method and Janbu method.The results showed that the first terrace slope is unstable,and the existed potential slip band is at a distance of about 13 m away from the slope edge.The second terrace slope is stable,and its limit dump height is 108 m.There are safety problems when the limit dump height is reached,therefore,reinforcement measures are needed.
