【 摘 要 】

The draw water tunnel of west line project is composed by tunnels group, the longest tunnel section is 73km, belonging to the super long tunnel. The tunnel construction method is TBM. The engineering geology and hydrological geology is complex along the tunnel, facing a lot of engineering geological problems in the excavation process, such as water inrush and rock burst. Through the TBM type selection factors analysis in West super long tunnel, drilling and blasting method and TBM methods are compared, the advantages and disadvantages between shield TBM and open type TBM are also be compared, the double shield TBM is selected as the construction machinery. At the end of the analysis, the adaptability to the formation of TBM is analyzed, and the improvement measures of TBM is put forward.
