Using the Information Quantity Method to Assess the Regional Risk of Highway Slope to Improve the Level of Risk Management

In recent years, there have been many studies on regional geological hazard risk assessment. However, most previous research focused natural disasters such as landslides and debris flows. There were few special aimed at highway slopes influenced deeply by artificial factors. According to the characteristics of slope, based evaluation influencing factors, factors engineering information an individual slope are introduced in this paper. The model, combined with analytic hierarchy process (AHP) ArcGIS spatial analysis, was used evaluate disaster study area. Then, assessment results zoning map along obtained. By comparing analyzing data management unit, good agreement actual slope. paper can effectively guide maintenance provide a reference for site selection subsequent reconstruction expansion projects. general, improve level engineering.
