    Abstract
  • The anti-dumping layered rock slope is a common type of slope, which has various deformation and failure modes, complicated mechanics mechanism and many influencing factors.In order to reveal the influence law of the geometric characteristic parameters in different fronting surface conditions on the flexural toppling deformation of the reversed inclined layered rock slope, this study used 3DEC to research the influence law of geometric characteristic parameters on flexural toppling deformation, combined with mathematical statistics system.The obtained results show that: ① The maximum deformation displacement is found on three faces of the slope and the minimum on one face; ② The deformation displacement of slope increases with slope height, slope angle and joint inclination, and it decreases with the increase of the included angle between the joint surface and the free face; ③ The deformation displacement of the slope is the largest when the angle between the two free faces is 90°; ④ The deformation displacement is the largest when joint inclination angle is 60° on the one and two free faces, and it increases with the joint inclination angle increasing.
