According to the situation of Yulin-Tieshangang Highway, twelve assessment factors are selected. The risk assessment can be divided into four grades: low grade, medium grade, medium-high grade, high grade. Based on GIS, the risk evaluation of collapse, landslide and karst collapse is carried out by the information value method and information value computation model of MORPAS 3.0. The risk of the highway geological disasters takes low grade to medium grade as a main part, high grade area is only in partial section. The geological disasters trend is light to medium. The evaluation is in accordance with the investigation.
