Abstract
Because the traditional slice method depends on an inexact assumption, stability analysis can be applied in slope engineering using another approach that involves the entire block without slicing. This approach is defined by the force-moment equilibrium system. The moment is converted into the integral of the force against the outline of the slope using the boundary integral. Because of the complexity of the irregular slope outline, a software program based on VC++ is developed for slope stability analysis. The software is programmed with a single document project, which embeds three complete modules for pretreatment, solution calculation and postprocessing. To visualize the parameters, graphics and output, a flexible software operation interface is created by enriching the class libraries and controls. The program is applicable to different types of slopes as well as complex algorithms. A sample analysis reveals that the safety coefficient is consistent with the analysis results of the most dangerous slip surface, which further verifies the accuracy and reliability of the software. Control points and single point search steps are set based on the previous custom slip surface (polyline). A series of safety coefficients are calculated over a certain area. Finally, the most dangerous slip surface of the slope is identified based on the control points corresponding to the minimal safety coefficients.
