Abstract The slope geohazard along Batang-Lhasa section of Sichuan-Tibet Highway is serious. Based on the slope disaster data collected over the years, the risk of typical slope geohazard along the section is analyzed by using several interpolation methods of geographical information system(GIS). The results show that the low, medium and high risk zones account for 78.9% of the total distance, with the whole distance of 1008 km, among which the high risk zone reaches 30.28%, and the distance of basically no risk zone is 270 km, making up 21.1%. The analysis results are reasonable and reliable through field verification.

Key words： highway slope geological hazard risk evaluation Sichuan-Tibet Highway
