Notes:
As a typical model of steep-tilt or moderate-tilt bedding rock slopes, buckling failurediffers greatly from tensile or shear failure. The mechanical characteristic of buckling failure isanalyzed, and the geo-mechanics model of buckling failure is put forward. The process of bucklingfailure includes three phases: slope terrane creep deformation, the lower of slope terrane benddeformation, and terrane structure collapse. Using pressure bar failure theory, a formulation forcalculating critical load of buckling failure is developed, which shows that critical load decreaseswith bend length increasing. The relationship between critical slope length and bend length isanalyzed. It is indicated that critical slope length decreases with bend length increasing, and thatcritical slope length reaches minimal value while critical load is zero. The minimal slope length canbe considered as a limit value while analyzing buckling failure of bedding slope, and its calculationequation is developed
