Abstract: As a typical consequent rock slope of Yuhuai Railway from DK385+470 to DK385+700,the failure mode is bedding slip with slippage of bedding plane. Because of not taking into account the contribution of slippage of bedding plane,the rigid critical equilibrium method for linear slip surface will cause the result of safety factor much great. According to the theory of upper bound limit analysis method,the author puts forward a new approach to deal with consequent rock slope stability analysis consid...
