[Abstract]:Deep and long tunnel is a key control project in the construction of large and super large traffic, mining and water conservancy projects. Its construction safety restricts the safety and progress of major national infrastructure construction, especially the deep mountains and valleys in the western region. It is difficult to use multiple drilling and blasting method in deep long tunnel construction. Considering the construction period, cost and technology, TBM construction method will become the best choice and inevitable development direction of deep long tunnel (lane) construction in western mountainous area, and the establishment is based on modernization. The safety risk management information system of underground engineering construction based on information technology is an important implementation countermeasure for tunnel and underground engineering construction safety management. TBM tunnel engineering 3D information system is an important part of underground engineering construction safety risk management information system research and application. Based on the project of 973 project "interaction mechanism and safety control of deep complex strata surrounding rock and TBM" (2014CB046905), aiming at the technical demand of TBM information construction management, this paper adopts the software rapid development tool Delphi and 3D graphic visualization technology. Through the research and development of the three-dimensional information bearing platform of tunnel engineering and the creation of application system based on the actual engineering data, the purpose of this paper is to provide an applied research platform for the safe construction of TBM tunnel project and provide technical support for the practical engineering information construction. The main research results obtained in this paper are as follows: (1) by analyzing the data structure and content of TBM tunnel engineering, the paper designs the data including the general situation of the project, geological borehole data, The database management system of monitoring project information and TBM tunnel support structure realizes the functions of data input, edit, query and output. (2) based on 3ds Max and GLScene, a rapid and efficient modeling method of seamless fusion of tunnel 3D strata and engineering is proposed. That is, based on borehole data, the basic 3D strata are first created by using GLScene, then the strata are divided and cut into 3ds Max. Finally, the mapping and rendering are introduced into GLScene to create and fuse the new engineering objects. (3) the functional framework of 3D information visualization system for tunnel engineering is designed. A 3D information visualization system for tunnel engineering is developed, which includes the main functions of 3D stratigraphic model and geological section information display, real-time rendering of 3D scene, interactive roaming, 3D object picking up and information query and statistics, etc. This paper provides a technical platform for further study of engineering application. (4) the main basic data of the main project of water conveyance tunnel based on ABH water transfer project 鈪，
