摘　　要：沪苏通长江大桥从建设至开通运营期间,积累了大量的监测数据、设计图纸等资料,如何利用BIM技术将这些数据信息与沪苏通长江大桥实体三维模型相关联,从而进行可视化展示及分析,是目前工程运营管理中亟须解决的问题。在监测数据可视化研究中,大多数都依赖于特定的三维软件,难以满足多用户、无插件、跨平台的使用需求,在铁路工程项目跨专业应用中的共享性较差。本文基于Cesium平台,采用Echarts、WebGL技术,针对沪苏通长江大桥主航道变形监测数据可视化需求分析,实现了沪苏通长江大桥主航道三维实体模型的搭建、监测点布设展示、交互式监测点变形信息查询等功能,为运营管理及工程人员提供了大桥实体监测点变形数据查询,能更加高效地对监测点变形规律进行分析,同时也能帮助决策者直观快速地了解大桥整体健康监测情况。During the period from the construction to the opening and operation of Shanghai-Suzhou-Nantong Yangtze river bridge,a large number of monitoring data,design drawings and other materials have been accumulated.How to use BIM technology to associate these data with 3D entity model of Shanghai-Suzhou-Nantong Yangtze River Bridge,so as to carry out visual display and analysis is an urgent problem to be solved in the current project operation management.In the research of monitoring data visualization,most of them rely on specific 3D software,which is difficult to meet the requirements of multi-user,plug-in free,cross-platform use,and poor sharing in the cross-professional application of railway engineering projects.In this paper,based on the Cesium platform,using Echarts and WebGL technology,aiming at the visualization demand analysis of deformation monitoring data of the main channel of Shanghai-Suzhou-Nantong Yangtze river bridge,the functions of building 3D entity model of the main channel of Shanghai-Suzhou-Nantong Yangtze river bridge,arranging and displaying monitoring points,and querying deformation information of interactive monitoring points are realized,which provides engineers with the bridge entity monitoring point deformation data query,which can more efficiently analyze the deformation law of the monitoring point,and also help decision-makers to intuitively and quickly understand the overall health monitoring situation of the bridge.
