【摘要】 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,侏罗系、白垩系、第三系红层软岩广泛分布于中国西部地区。地质环境条件是形成红层软岩滑坡的控制性因素,岩体强度特征决定滑坡的力学变形机制。不同变形、破坏条件影响红层软岩滑坡运移机制与特征。红层软岩岩层层面在各种地质营力的长期作用下逐步演化为滑动面。本文在区域研究的基础上,对中国红层软岩滑坡的基本特征进行了系统研究。更多还原

【Abstract】 Red-soft-mudstone layer landslides of Jurassic and Cretaceous and Tertiary are distributed in north china widely. It is the basic characteristic of red-soft-mudstone layer with weak anti-weathering capability, feeble rock mass strength, rather bad engineering geological property, and it is very sensitive to water generally, landslide hazards in this area is very serious. Geological environmental conditions of the red-mudstone layer landslides are the key factors for forming landslides, rock mass strength characteristics determined the mechanical and deforming mechanism of landslides. The traits and moving characteristics of red-mudstone layer landslide varied with different conditions of deformation and failure. Based on the study of rock mass strength in different failing conditions and shear strength of rock layer surface, this article analyzed the mechanisms of creeping deformation and slip plane forming systemically, the basic characteristic of the red-soft-mudstone layer landslide was given after the studies and statistic analysis of typical red-soft-mudstone layer landslide examples.更多还原
