In conventional slope stability analysis

the slope stabilities for various cross-sections are calculated independently. ObjectiveTo improve the calculation efficiency of slope stabilities for multiple profiles

this study prop oses a method based on spatial slope stability coefficient calculations. MethodsThe two-dimensional residual thrust method is incorporated with spatial profiles

which forms a residual thrust method for spatial profiles. MethodsThe calculation process of the residual thrust method for spatial profiles is optimized by the automatic generation and management of profiles within a three-dimensional engineering geological mode of a slope. In order to achieve rapid and efficient calculation of slope stability coefficients

a method based on multi-threaded parallel computation is introduced. Combining this approach with the residual thrust method for spatial profiles allows for more accurate and efficient computation of stability coefficients for multiple spatial profiles. ResultsUsing an 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. On this basis

seven spatial profiles are automatically generated

and stability coefficients are calculated using multi-threaded parallel computation. Finally

the results are presented visually. ConclusionThe research findings indicate that adopting multi-threaded parallel computation for calculating slope stability coefficients for multiple profiles can fully utilize computing resources and significantly improve computational efficiency. Furthermore

application in engineering projects confirms the feasibility and applicability of the proposed method.
