| Abstract: | Based on the elastic differential equation of flexural slumping rock layer in layered dip rocky slope and its accurate solution, the critical length expression of flexural slumping rock layer is established with energy method; and the major influencing factors are summarized and their first and secondary relationships are analyzed through predominance analysis. The results show that in significant order the thickness of a single rock layer, the physical properties, the slope angle and the elastic modulus of rock mass are the major influencing factors to the critical length of flexural slumping rock layer . |

| Keywords: | layered dip rocky slope flexural slumping critical length influencing factor |
