Design and Implementation of Highway Traffic Geological Hazard Information Model Database

摘要

Geological hazard is one of the main facts which will influence the safety of traffic in mountainous areas. In order to investigate the temporal-spatial distribution of geo-hazards along highways, in this paper a geo-hazard information model is put forward to construct the database of geological hazard based on GIS technology. The database includes three-dimensional spatial database of geo-hazards and attribute database, which are connected by "UnifiedCode". Finally, taking the Ya'an-Kangding Expressway as an example, the structure and content of database is given. The results show that the database can meet the requirements of standardized management of geo-hazards and provide direct data support for the study of regional geo-hazards distribution and hazards zoning.
