Abstract Based on series of experiment researches on the engineering geological properties of Badong red beds，the formulae of stability coefficient on different positions of potential sliding surface are established by the mode of plane sliding which is most commonly used for this kind of slope. Combining with the calculation of the examples，the analysis of influence of excavation on slope stability is conducted and the shear rheological process of weak intercalation on the potential sliding surface is analyzed. The research results show that the failure of Badong red bed soft rock gently inclined bedding slope begins at the excavation of slope foot，and intends to potential sliding surface. The process starts from constant rate creep，gradually to accelerated sliding，which comes with the interaction of many factors，such as disintegration of rock mass，crack growth and water infiltration softening the potential sliding surface. On the basis of grasping the failure mechanism of this kind of slope，the related recommendations on the reinforcement means and construction managements are proposed and the research results have significant referenced values for the similar slope.

Key words： slope engineering red bed soft rock gently inclined bedding slope progressive failure weak intercalation
