Study on Visualization System of Construction Control of Long-span Continuous Rigid-frame Bridge

为了提升桥梁施工管控水平,实时了解桥梁施工实时动态,依托互联网平台,创建了一套云端三维可视化信息管控系统。针对波形钢腹板桥梁施工控制精度高、控制难度大的特点,开发了一套基于B/S(浏览器/服务器)架构的施工控制管控软件,帮助管理人员更加直观地获知现场结构状态,提升施工管控效率。该系统将二维平面化信息与三维实体深度融合,通过在三维场景中高度还原真实桥梁施工状态,实现信息流的立体化展示。研究结果表明:系统能够通过线形预测,协助管理人员进行施工管理,提高工程效率;系统能够实现大跨径连续刚构桥三维模型动态演示与施工测控数据与进度信息图形化展示。

In order to improve the management and control level of bridge construction and understand the real-time dynamics of bridge construction in real time,a set of cloud 3D visualization information management and control system is created based on the Internet platform.In view of the characteristics of high precision and great difficulty in the construction control of corrugated steel web bridge,a set of construction management and control software based on B/S(browser/server)architecture is developed to help the managers more intuitively learn the site structure state and improve the efficiency of construction management and control.The system deeply integrates the two-dimensional plane information with the three-dimensional entity and realizes the three-dimensional display of information flow by highly restoring the real bridge construction state in the three-dimensional scene.The results show that the system can assist the management personnel to carry out the construction management and improve the engineering efficiency through the linear prediction.The system can realize the 3D model dynamic demonstration,and the graphical display of the construction measurement and control data and progress information of long-span continuous rigid-frame bridge.
