摘要
针对白云鄂博铁矿东矿C区边坡产生的3处不稳定滑体,结合现场工程地质勘察和岩石力学试验,采用理正岩土分析软件5.5版及加拿大岩质边坡稳定性分析计算软件SLIDE5.0对削坡、锚索加固、注浆的二次加固措施进行了分析计算,通过计算得到的安全系数来综合判断该二次加固措施的有效性。分析计算结果表明,通过削坡、锚索加固、注浆的加固措施,可以使白云鄂博铁矿东矿C区边坡最危险滑面的安全系数达到1.186,符合设计边坡稳定安全系数要求。文章最后提出了实施这些措施时的注意事项。
For three unstable landslides of C area of Bayan Obo Iron Mine, with data of engineering geological exploration and rock mechanics test, the paper analyzed and calculated several measures for the secondary reinforcement including cutting slope, reinforcement by anchor cable and grouting by use of 5.5 edition of Lizheng soil analysis software and Canadian rock slope stability analysis software SLIDES. 0, and determined whether the secondary reinforcement measures are effective through the calculated safety factor. The analysis and calculation result showed that the secondary reinforcement measures can make safety factor of the most dangerous landslide to achieve 1. 186, which meets requirement of designing safety factor of landslide＇s stability. At last, it proposed several notices about implementation of the secondary reinforcement measures.
