摘　　要：为解决鞍钢齐大山铁矿5号运矿胶带上部边坡存在的安全隐患,针对边坡的岩性构成、岩体结构进行了调查与分析,确定了整体边坡和台阶边坡的破坏模式与危害,通过稳定性计算分析得出了边坡稳定性状态,综合考虑边坡破坏模式、空间形态、服务年限、施工工期等因素的影响,最终确定边坡治理方案为12m全长粘结锚杆与SNS主动柔性防护网相结合的边坡主动加固措施。To solve the hidden safe trouble of No. 5 ore conveyor belt upper slope, the investigation and analysis of lithologic composition and rock mass structure has been carried on. According to investigation and analysis results of lithologic composition and rock mass structure type, it was determined to the failure mode and harm of whole slope and Bench Slope. Through the calculation and analysis of slope stability, the stability state was determined. By comprehensive consideration influence of such factors as slope failure mode, Spatial Form, service life, construction period, the final slope control plans will be comprehensive reinforcement measures with 12m whole--length cohesive anchor bolt and SNS actively flexible defend net.
