Abstract：The limit equilibrium method based on cantilever beam theory is a feasible method for analyzing flexural toppling in anti-dip layered rock slopes. However，most of the current calculation methods are iterated successively for all strata on the failure surface，which often requires a lot of mathematical calculation.It is difficult to evaluate the slope stability in the field quickly and preliminarily. Based on cantilever beam theory，the rock columns above the failure surface are divided into three sections：the stable section，the active toppling section and the passive toppling section by comparing the critical instability height with the present height of the block on the failure surface. Based on the limit equilibrium，the corresponding stability calculation method is proposed，and the risk of toppling failure can be preliminarily determined by using the geometric area of S area. 2 engineering examples and centrifuge experiments were illustrated for practical verification of the proposed approach. The research results of this paper have guiding significance and application value for the stability evaluation of flexural-toppling failure in rock slope.
