Abstract

Abstract

The deformation and stability of rock slope are very important to engineering construction. Taking the right bank bedding rock slope of a hydropower project on Yalongjiang River as an example, in this paper it studies and summarizes the formation mechanism, development characteristics and the relationship with weak structural plane dip and development depth of sliding-shearing deformation and failure mode by in-situ investigation, theoretical analysis and numerical calculation. The research results show that sliding-shearing deformation and failure mode usually occurs in the bedding rock slope with poor mechanical properties or in the strong-weak weathering rock masses. The sliding-shearing deformation and failure of rock mass slope are closely related to the dip and development position of steep weak structural plane. The weak structural plane with 45°-65° dip or horizontal distance of less than 80 m from the slope surface is obviously influence to sliding-shearing deformation and failure of slope, and the influence of the horizontal distance between the weak structural plane and the slope surface is stronger than dip of weak structural plane on sliding-shearing deformation and failure of slope. This study is of great engineering significance and practical value to supplement the deformation and failure types of rock slope.
