Summary:The invention discloses a soil slope stability analysis method based on an accurate finite element method. The soil slope stability analysis method comprises the following steps: establishing a two-dimensional slope model and dividing grids; judging whether the soil body yields or not by adopting a corrected hyperbolic arc Mohr-Coulomb yield constitutive, if the soil body yields, carrying out stress redistribution by adopting an accurate display Euler algorithm, and always ensuring that a stress point is on a yield surface or in the surface through stress pull-back; for the solution of the nonlinear equation set, Newton-Raphson iteration is adopted for solution; a strength reduction method is introduced, damage criteria with enough precision requirements are adopted, the safety coefficient of the slope is obtained through iterative search, and data such as displacement and plastic zones of the slope can be obtained by post-processing results. According to the method, the stability analysis of the slope is rea
