Abstract: Based on MapGIS-TDE platform, aimed to the highway slope model building, the “entity-oriented spatial data model based on feature” which has good adaptability and flexibility is applied to achieve the data organization and storage. Using the survey and design data of highway, the 3D model building methods of the slope surface, ground and underground are presented; the sub-model building methods of the unexcavated slope, excavated road and excavated slope are also discussed for building terrain model. In addition, based on the surface displacement and rainfall monitoring data, 3D real-time inquiry and statistics are available to provide real-time analysis for highway landslide monitoring and precaution. The 3D slope model of the Changde－Jishou expressway in Hunan province has been established by this method.

Key words: highway slope, 3D modeling, visualization
