| 摘 要： | 简要介绍了边坡岩体质量分类的SMR法,将之应用于2个典型楔形体破坏模式下红层岩体高边坡稳定性宏观评价。 指出在评价过程中要注意对边坡起控制作用的优势结构面,并将其作为SMR法中结构面项评分的主要依据,这样得出的评分 值与边坡的实际情况才会比较相符。对地应力的影响进行了定性的分析,指出高地应力地区边坡SMR法应该慎用。

| Abstract: | The SMR system for classification of slope rock masses is briefly introduced and applied in two representative wedge sliding red rock slopes to the stability of macroscopical evaluation. In the course of evaluation,great importance should be attached to predominant structural planes that dominate the slope failure, and these predominant structural planes shoud be taken as dominating component in structural plane evaluctin in the SMR system, which would lead to a good SMR consistent with the fact of slope failure. The effect of in-situ stress is analysed qualitatively, and the result indicates that the SMR system should be applied very carefully in high in-situ stress area. |
