Abstract：In order to study the influence of different section forms of the open-pit mine slope on the slope stability,taking the south slope of Heishan Open-pit Mine as an example,based on the optimization method theory of the simplified Bishop method and the numerical simulation study of the strength reduction method,the article analyzes numerical variation relationship between the anti sliding force and the sliding force of the slope under different section shapes,explores the stability relationship of the slope under different section shapes,and proposes the slope section shape optimization method.The results show that there is a bottom dip angle θ,the slope is divided into"anti sliding section"and"sliding section".When the difference of slope section form is mainly distributed in the sliding section,it is not conducive to the slope stability.When the difference of slope section shape is mainly distributed in the anti sliding section,it is conducive to the slope stability.
