Abstract
Based on the practical application of Geology Information System(GIS) throughout the world, combined with the characters of road’s geological hazard and it’s supervision, the paper introduces on the importance of the research on road’s geological hazards information management and decision-making support system. The paper also analyzes the system’s target, the principles and key techniques in developing the system. In the research, we developed the GIS-based road’s geological hazard information management and decision-making support system and applied it to one speedway in the west of China where contains typical geological hazards. The system based on the database of road’s geological hazard on the grounds of spatial graphic information and attribute information. By virtue of the scientific assessment and prediction mathematical model, integrating the GIS’s strongpoint on spatial analyzing, the system is capable of visualizing the regionalization of road according to the geological hazards it contains, and accurately assessing and predicting geological hazards, thus efficiently assists the road construction and management units in the decision making on controlling the geological hazards and reducing the related loss.
