To evaluate the stability of rocky slopes in the high-altitude, cold, and High seismic intensity terrain of the Kunlun Mountain region, we analyzed key factors influencing the stability of these slopes in relation to a specific highway project in the area. Four primary indicators, including slope morphology, meteorological and hydrological conditions, rock characteristics, and triggering factors, were selected, along with 16 secondary indicators, as fuzzy evaluation criteria. Based on the entropy weighting-fuzzy theory, we established a stability assessment model for rocky slopes in this region. Finally, taking the rocky slope section K128+540-K128+560 as an example, we used the evaluation model to calculate a 51.71% probability of slope instability. The evaluation results align with the actual on-site conditions, providing valuable insights and practical implications for analyzing and evaluating the stability of similar rocky slopes in this region and other projects.
