基于BIM-WebGIS的边坡管理系统关键技术研究

Research on Visualization Management System of Slope Based On BIM and WebGIS Technology

随着交通基础建设不断向山地、丘陵地区发展,大量的天然及人工边坡已经成为影响铁路、公路建设和运营安全的重要因素。为提高边坡监测管理效率,研究了边坡BIM模型创建方案,提出了含属性信息的跨平台BIM数据存储格式,实现了模型数据与空间数据在WebGIS环境下的集成,并开发了基于BIM-WebGIS的边坡可视化管理系统。依托该系统进行边坡多场景、全生命周期管理,能够有效减小边坡灾害对交通建设和运营的风险。

As the transportation infrastructure is constantly developing to mountainous and hilly areas,a large number of slopes have become an important factor affecting railway,highway construction and its operational safety.In order to improve the efficiency of slope monitoring and management,this paper adopts the combination of BIM technology and WebGIS technology,proposes the geological modeling method of slopes based on BIM,researches the lightweight export standard of BIM model containing attribute information,realizes the integrated application of the BIM data in the WebGIS environment.Then,the slope visualization management system based on BIM and WebGIS technology was developed.Based on this system,the multi-level,multi-dimensional and full life cycle management of slopes can reduce the risk of slope hazards to transportation construction and operation.
