Abstract: The geological conditions along the Hanhuang Expressway are complex, and geological disasters such as collapses, landslides and mined-out subsidence are developed. In this study, the fuzzy comprehensive evaluation method was adopted, which comprehensively considered multiple factors such as topography and landform, rock and soil mass type, slope structure, human engineering activities, precipitation, development status and prediction and evaluation of geological hazards, combined with field survey data and geological data, to quantitatively analyze and classify the risk of geological disasters along the line. The results show that there are 3 hazard levels and 70 sections along the highway, of which the hazard area accounts for 16.62% of the total length of the line, the medium hazard area accounts for 19.29%, and the relatively less hazard area accounts for 64.09%. In view of the geological disasters in different grades, targeted prevention and control measures are proposed, including the monitoring and treatment of collapse, the avoidance and engineering treatment of landslides, and various treatment schemes of goaf collapse. This study provides a scientific basis for the risk assessment and prevention of geological disasters on the Hanhuang Expressway.
