Abstract
The traditional limit equilibrium slice method does not consider the distribution of the interslice normal force when analyzing the slope stability. That is, the present invention takes into consideration the distribution of the acting positions of the thrust line, and thus provides a slope stability limit equilibrium calculation method based on the distribution characteristics of the interslice normal force. For the deep concave slip surface, it is found that the improved limit equilibrium method and the traditional limit equilibrium method have a large error in the safety factor, which is as high as about 20%. The method of the present invention has the characteristics of simplicity and reliability, and will provide more accurate results for slope stability analysis.
