Research And Application Of A Intelligent Visualization System For Monitoring The Information Of Tunnel Construction

Currently, with the advancement of economy, the environment of traffic is increasing severe. In order to improve the survival environment, the development of underground space has become the inevitable trend, how to develop and exploit the underground space have become a hot-button issue on various of domains, and simultaneously it also has significant values of the society and economy.The design and construction of the tunnel have brought in plenty of the New Austrian Tunneling Method. During the building of the tunnel, the information is pretty huge due to the uniqueness, periodicity and chronicity in monitoring the deformation of the structure. The management of information is one of significant jobs in monitoring the deformation of the structure and the way of current management is low-efficient. During the construction of the tunnel, the performance of the surrounding rock is quite complex and invariable, the mechanics parameter of the surrounding rock is difficult to supply, the analysis of the monitor of the data and the feedback analysis of the construction period of the tunnel involves professional analysis, complex data process and a huge amount of calculating time. In the ocean of numerous and abstract data, the managers of the construction are always confused deeply.Through the research and establishment of the intellectual and visual system of the monitoring information in the process of the tunnel construction, this essay can manage and monitor the information effectively and properly as well as analyze and forecast the stability of the structure of the subway and the tunnel in time, and combine the engineering example of Da Lian subway and Bai Jia Po tunnel, basing on the New Austrian Tunneling Method, and designed the information management of engineering database and VTK visualization presentation system which possess the function of the storage of statistic in deformation and monitor, preprocess, management analysis, limit values alert, automatic monitor prewarning, differential evolution intelligent back-analysis, and finite element numerical simulations were conducted by using the mechanics parameter in the back-analysis. In the meanwhile, the numerical simulation results for example stress, displacement are reflected on the VTK visualization presentation system patented technologies ourselves so that the results are more clear and the construction organization can be conducted to use the reasonable additional solutions and measures in the construction, ensuring the safety and process of the project.
