This paper starts from the radial strips, establishes the inter-strip force model, combines limit equilibrium and plastic limit analysis, does not need to make assumptions about the inter-strip force, and can easily calculate the total reaction force at the bottom of the sliding body, so that the slope is stable, stable and safe. The coefficient is simple and convenient to calculate the formula, the calculation method is simple, its operation and calculation are as simple as the Swedish method, without trial calculation, there is no non-convergence and failure condition, and it is worthy of popularization and application. The calculation example is compared with the result of [1].

In this paper, from the radial strip cut-in, the establishment of inter-bar force model, the joint use of limit balance and plastic ity limit analysis, no need to make assumptions about the inter-bar force, can be easily sought out the bottom of the slide body total reaction force, so as to arrive at the slope stability and safety factor simple calculation formula, the calculation method is simple, its operation, calculation and Swedish method is simple, no need to try, there is no non-convergence and failure, worthy of promotion and application. The study is compared with the results of the text.

In this paper, starting from the radial slice, a model of inter slice force is established. By using limit equilibrium and plastic limit analysis, the total reaction force at the bottom of sliding mass can be easily calculated without assuming the inter slice force. The calculation method is simple, and its operation and calculation are as simple as those of Sweden method. There is no need for trial calculation and there is no non convergence and failure It is worth popularizing and applying. The example is compared with the results in [1].<br>
