Abstract:Research purposes: TBM construction of large tunnel has been applied in the subway, hydropower, municipal, highway, railway and other projects. Due to its complex structure and poor working conditions, under the influence of factors such as the decision-making errors, insufficient risk estimate, and site operation error, some abnormal situation easily appeared in the TBM tunneling process, which may affect the construction schedule, or cause major accidents. A great deal of research has been carried out on TBM construction information monitoring technology by scholars at home and abroad, and some achievements have been achieved. However, the achievements are mainly focused on real-time monitoring, which can only reflect the operation status of TBM and the general situation of construction site, and lack of key functions such as data processing and analysis, risk warning, business management, feedback and guidance of construction. Based on Gaoligong Mountain tunnel of Dali-Ruili Railway, this paper studies and develops the railway tunnel TBM construction information monitoring system, which provides a foundation for safe tunneling and systematic management of TBM. Research conclusions: (1) The overall architecture of TBM construction information monitoring system is composed of 5 parts, including business architecture, logical architecture, data architecture, technical architecture and functional architecture, with comprehensive and reasonable design. (2) The security protection level of the railway tunnel TBM construction information monitoring system is the third level, and the systems are all deployed in the main data center of China Railway. The existing security measures of the main data center are fully utilized and the network security protection technology system is constructed based on the actual needs. (3) TBM construction monitoring system adopts file interface and OPC interface to extract TBM construction data. (4) The data automatically collected by TBM is transmitted to the computer of the project department in real time, and then transmitted to the server through the Internet. Users can read and analyze TBM construction data in real time by accessing the server. (5) Gaoligong Mountain tunnel plays an important role in reducing construction risks and accelerating information communication between construction site and management through application practice. (6) The research results can be applied in TBM construction of similar tunnels.
