摘要
对湘西高速公路红砂岩边坡进行稳定性分析时,采用传统的SMR评价体系,发现其结果与实际差别较大,出现了体系评分偏高,实际坡体稳定性差甚至发生滑坡现象。经过SMR体系分析,并结合工程实例对比研究,考虑到结构面充填物对边坡稳定性所起的重要作用,对SMR法的F3值进行修正,提出了一种用于红砂岩边坡的HSMR评价体系。
In stability analysis of red sandstone slope in Xiangxi Expressway,it is found that the result of slope stability using traditional SMR evaluation system largely differs from the actual result.The evaluation score is higher,but the actual slope stability is poor or even landslide occurred.Through comparison of SMR system and practical engineering,considering the important effect of filling material in structural face on slope stability,F3 value of SMR method is revised and HSMR evaluation system is put forward for red sandstone slope.
