Research Of Key Technologies Of Visual Tunnel Construction Information Platform

Tunnel construction is a very complicated management process,which will accumulate a large number of abstract,multi-dimensional and disorderly construction data.Therefore,with the help of information technology,communication technology and control technology,the tunnel construction information platform is developed to digitize the relevant data of tunnel construction,which is necessary and urgent.However,in the existing research,the application of data visualization and the application of technology still stay in the early stage of the data information management system,mainly in the form of static presentation,including text,tables,network diagrams,etc.,even if there is a related 3D model display,The information also has large delays and incompleteness,which brings great uncertainty to the manager's decision-making.It can't monitor the tunnel construction in real time.At the same time,it needs manual sorting and processing.It brings great inconvenience to the construction system and increases the cost of data management.Therefore,only the 3D model can be dynamically and real-time correlated with the construction data,allowing the user to observe and interact in real time,making the data monitoring results more intuitive and the data presentation method more abundant,can more efficient management be realized and management can be improved.Based on the above problems of construction information platform,this paper uses virtual simulation technology,visualization technology and Web technology to combine with traditional tunnel construction to develop a visual tunnel construction information platform.First of all,the platform can display the data generated in the actual construction scene in a way of mixing the 3Dmodel and the 2D chart,and the platform has the characteristics of real-time dynamic evolution of the data-driven 3D model,which can make the virtual construction scene keep pace with the actual construction,and enhance the intuitiveness of construction data monitoring.Secondly,the construction data is monitored in real time by manual or automatic means,and the abnormal data is alerted.Finally,this study also provides a platform aid tool App to assist the platform for mobile office,and achieve effective organization and efficient management of tunnel construction information data.In addition to the above research content,in order to verify the usefulness of the research,a railway tunnel construction project was introduced into the platform.The result shows that the platform can effectively improve the management level of tunnel construction information and has important economic and social significance.
