沉管隧道管节的浮运、沉放及对接等是整个沉管隧道施工中的重中之重，这几个工序主要集中在水下进行，当前施工技术难以全面控制施工过程及其对接精度等，研究沉管隧道施工的可视化监测系统，对辅助现场精确测量、潜水作业以及指导安全管理施工具有重要的意义。针对沉管隧道施工工艺的特殊性，基于 VTK 的可视化和数据模型驱动等关键技术，采用并集成 GPS 测点坐标系统的构建与精确转换、PSM 配置，设计和开发了一种沉管隧道施工三维实时可视化远程监测系统，可以实时显示和查询施工过程中管节浮运、沉放的具体情况，实现沉管隧道实时可视化，并将该系统成功地应用于天津市海河沉管隧道工程的施工中。

In the process of immersed tube tunnel construction,floating and sinking are among the main priorities carried out underwater.The current construction technology cannot adequately or accurately control the floating and sinking processes,because the construction is carried out-un-derwater.The result of this is the work must be done by hand.The visualization system of im-mersed tube tunnel construction based on remote real-time monitoring is helpful in assisting with the measurements in construction sites and checking the results of diving operations for the dis-tance of abutting points.This makes this visualization system greatly significant and useful in maintaining the safety and management of the construction in the immersed tube tunnel.The con-struction is unique because of its floating and sinking processes.In this paper,a series of key tech-nologies are employed and integrated,including the establishment of the measuring point coordi-nate system making use of GPS and accurately converting coordinates,the use of the PSM config-uration,visualization technology based on VTK,Autodesk 3DS Studio MAX,model-driven data, Microsoft SQL Server Express,and others.A three-dimensional visualization system of immersed tube tunnel construction based on remote real-time monitoring is designed and developed by com-bining these key technologies.The system includes a GPS testing system in the pipe section and a dip angle system in the construction site for the processes of floating and sinking.The database of Microsoft SQL Server Express is included in the control center,along with the SOAP Web Service protocol communication.More specifically,the system can display the real-time situation of a sec-tion of pipe on the construction site,inquire about a great deal of information concerning the pipe section,and play back any time sequence of the construction process.The presented visualization system realizes the function of remote real-time monitoring for the tube’s floating and sinking, and it is successfully applied to the construction of the Haihe River immersed tube tunnel engi-neering in Tianjin.Its results closely match the information from the construction technical per-sonnel and can reflect the pipe section’s real-time situation and tendency in the toleration of the engineering error range.In addition,the system provides a guarantee for the safety and efficiency of the construction and can be further applied to related engineering projects.
