Abstract

Taking Shanyang rockslide in Shaanxi province for example, the apparent dip slide characteristics, and creep-buckling failure mode and mechanism of steep stratified oblique rock are analyzed. Based on the beam theory and mechanical model of bending-buckling failure of stratified slab-rent structure rockmass, the mechanical model of buckling failure of steep stratified oblique rock is established through structural-mechanical analysis of rock mass, taking into consideration of gravity of slope, hydrostatic pressure of groundwater and lateral friction of apparent dip slide of inclined bedding rock. The corresponding condition equation of buckling length is derived afterwards. The result of checking computation on Shanyang rockslide is basically consistent with the practical result, which indicates that the condition equation is correct. And it can provide references for the prevention of apparent dip buckling failure of steep stratified oblique rock.
- steep stratified oblique rock,
- apparent dip buckling failure,
- lateral friction,
- condition equation
