Analysis of Failure Mechanism of Sliding and Bending of Red Bed Slope under Uplift Force
The red bed soft rock has unique engineering characteristics,and there are many cases of its consequent slope instability.Based on the constitutive equation of elastic deformation of rock mass,this paper deduces the calculation formula of the ultimate bearing capacity,the ultimate slope length and the position of the bending point of the red bed slope under the condition of rainfall,and the criterion of the sliding bending failure of the red bed soft rock slope,and validates the relevant conclusions with the example of a large gently inclined bedding landslide in southern and western Hunan.The relevant conclusions have important reference value for the investigation and pre-reinforcement of similar projects in the future.
