Abstract: In view of the short construction period and complicated geological conditions of mountainous expressway projects, the traditional slope stability research methods and analysis methods are too cumbersome, and new approaches and ideas must be sought.Based on the fuzzy comprehensive evaluation method and the analytic hierarchy process, a rapid evaluation method for the slope stability of the expressway in mountainous areas is proposed.On this basis, using GIS technology, connecting the database SQL Server through ArcSDE,using C# as the programming language in Visual Studio and combining with ArcGIS Engine, a set of rapid evaluation system for the slope stability of mountain expressways for different users has been developed.The system is applied to the evaluation and analysis of slope stability along the Wuyu Expressway, and the results of the system evaluation have a high consistency with the actual project, indicating that the system has a certain degree of reliability and practicability and has wide promotion value in road disaster prevention and control in mountainous areas.
