Research And Development Of Highway Slope Maintenance Management System Based On WebGIS

With the increasing scale of China’s expressway network and the increasing mileage of expressways in mountainous areas,the problems of highway slope disasters are increasing day by day,and the types of disasters are diversified.The complexity and difficulty of highway slope maintenance and management are increasing day by day.The establishment of highway slope maintenance management system is helpful to find slope diseases in time,allocate slope maintenance resources reasonably and make slope maintenance decisions scientifically.However,in the existing highway slope maintenance management system,there are some problems,such as scattered slope maintenance information,inconsistent data standards,low visualization degree,and difficulty in organically combining massive maintenance information with slope safety risk assessment.In view of the above problems,this paper designs and implements a highway slope maintenance management system based on WebGIS.The main research contents are as follows:(1)Based on the design idea of B/S architecture and separation of front and back ends,Using Vue.js and Koa2 as the development framework,combined with Baidu map API,Element-UI style component library,ECharts chart,Mongo DB database and other technologies,a highway slope maintenance management system is designed and implemented,which integrates slope geographic information platform,multi-source data visualization Kanban,slope maintenance information management,slope automatic monitoring,slope evaluation and decision-making and other functional modules.(2)The system takes WebGIS technology as the core,extracts multi-source data information such as geographic location information,safety risk category,maintenance information,real-time monitoring data,etc.from all slopes along the macro expressway network to a micro single slope,and displays them on satellite maps,providing a visual spatial information platform for slope inspection and maintenance management.(3)Based on the requirements of highway slope maintenance and safety risk assessment,the slope inspection method and maintenance information standard are designed.On this basis,aiming at different slope safety risk evaluation indexes,the functions of multi-source data mining and selection suggestions are realized,which provides support for experts to scientifically and efficiently evaluate slope safety risk categories.This paper studies and develops a highway slope maintenance management system based on WebGIS,establishes an API that conforms to the REST standard,has good scalability and maintainability,and realizes the standardization of slope maintenance information collection,slope data visualization,maintenance management information,high efficiency of slope inspection,intelligent safety risk assessment and scientific maintenance decision-making.So as to effectively prevent the occurrence of highway slope disasters,fully ensure the safety and smoothness of highway traffic,provide an important research reference and systematic application example for highway slope maintenance management,and have important reference value for disaster prevention and mitigation management in China.
