| 摘 要： | 我国西北部地区白垩系、第三系红层软岩广泛分布，红层软岩岩体强度低、抗风化能力弱、水敏感性强、工程地质性质较差、滑坡灾害严重．本文在研究红层软岩不同破坏条件下岩体强度特征的基础上，系统分析了红层软岩滑坡的蠕动变形与滑动面形成机制，经对典型滑坡实例统计分析，从定性和定量两方面论述了红层软岩滑坡的运移机制．

| Abstract: | Red-mudstone layer landslides of Cretaceous and Tertiary are widely distributed in northwest China. The anti-weathering capability of the red-mudstone layer is relatively weak, its rock mass strength is feeble, and it is very sensitive to water. The engineering geological property of the red-mudstone layer is bad and landslide hazards in this area are numerous. Based on a study of the characteristics of rock mass strength in different failing conditions, this article systemically analyzed the mechanisms of creeping deformation and slip plane formation. The elemental characteristics of red-mudstone layer landslides were discussed in two the aspects of qualitative and quantitative analysis according to the above study and statistic analysis of typical landslide examples. |
