Shanxi Highway Earthquake Disaster Risk Division Based on GIS

Abstract:

The paper take Shanxi Province as the object of study, through the analysis of the type after shaking the Shanxi Province road secondary geology disaster, the distribution rule and send the disaster mechanism's investigation and the analysis, the Shanxi Province earthquake secondary disaster mainly have the pitch geology disaster, the mud-rock flow disaster as well as the roadbed cave in three broad headings. The paper selection earthquake intensity, the terrain slope, the ground type, the surface cutting density, the surface cutting depth, the vegetation, the drainage density, the rainfall amount and so on take the pitch geology disaster's risk evaluating indicator, established three has ordered by type lives the geological disaster risk evaluating indicator system and the rank division system, and determined each influencing factor the weight. Has completed each influencing factor topic chart level using the GIS technology, through the GIS spatial analysis function, the superimposition has completed each kind of disaster's risk factor index chart. Finally can obtained the figure of shaanxi roadbed disaster risk classification.
