| TBM technology (full face tunnel boring technology) mainly use mechanical pressure on the land of rock cutting, crushing, is a high degree of mechanization and automation of large underground tunnel excavation equipment, its technical complexity, high efficiency, speed, quality, safety and other advantages. TBM technology is a new type of tunnel construction technology, it mainly thought the core equipment to large-scale modernization of the transport machinery for the auxiliary equipment load, using TBM construction method, boring, tapping, lining, filling and other processes completed at once, molding the whole section at once, construction progress fast, good security, ventilation requirements low, less Lining Project.The full collection of previous research based on fuzzy in engineering in this paper, to study the TBM tunnel project in the application of water, the main content is following(1) System analysis established the structure of TBM mechanical composition of TBM, study rock breaking mechanism and the efficiency of the main driving factors, including geological factors.(2) Study the TBM selection comprehensive and analysis some of the key technologies of the actual TBM construction method. Major adverse geological conditions for construction and open-type TBM construction in the early stages of supporting technology.(3) Focusing on construction of slurry shield TBM technology, provides a theoretical basis for application of Dahuofang tunnel(4) Combine of Dahuofang tunnel to analysis in the tunnel during the construction of shield TBM difficult and key technical issues and put forward counter measures. |
