Abstract In the present paper, the digital image processing (DIP) technology is employed to establish the structure model of a real SRM (soil-rock-mixture) slope. Based on the structure model, the most recently developed strength reduction numerical manifold method (SRNMM) is adopted to investigate the stability of the SRM slope. Based on the proposed numerical model, the testing results show that: 1) the DIP technology can accurately build the structure model of the SRM slope; 2) the SRNMM can obtain the slopes’ FOSs (factors of safety) with satisfactory accuracy, as well as obtain the main failure mode of the slopes; 3) the presence of rock blocks will improve the stability of the soil slopes.
