In slope stability analysis, the conventional practice involves independently calculating slope stability for various cross-sections.
To enhance the efficiency of slope stability system calculations for multiple profiles, this study introduces a method based on spatial slope stability coefficient calculations. Initially, the two-dimensional residual thrust method is expanded to incorporate spatial profiles, resulting in the residual thrust method for spatial profiles.
Subsequently, the calculation process is further optimized by realizing the automatic generation and management of the profile on the 3D slope engineering geological model. To achieve swift and efficient calculation of slope stability coefficients, a method based on multi-threaded parallel computation is introduced. Combining this with the residual thrust method for spatial profiles allows for more precise and efficient computation of stability coefficients for multiple spatial profiles.
Using a specific open-pit mine in Xilinhot, Inner Mongolia as a case study, we establish a three-dimensional slope engineering geological model for the internal dump site slope. Seven spatial profiles are automatically generated and stability coefficients are calculated using multi-threaded parallel computation. Finally, we present visual results through visualization techniques.
The research findings suggest that adopting multi-threaded parallel computation for computing slope stability coefficients of multiple profiles can fully utilize computing resources and significantly improve computational efficiency. Furthermore, practical implementation of this method in engineering projects affirms its applicability and feasibility.
