Abstract：Research purposes：The Dahuofang water tunnel is a super long deep-buried tunnel with the length of main tunnel of 85.32 km and excavation diameter of 8.03 m. TBM was used as main construction method along with bored blasting method for construction of the tunnel. As the tunnel passed through the area with complicated hydrogeologic conditions, it was necessary to do the works of TBM type-selection and optimization of the support system so as to solve the technical problems related to the stability of surrounding rock, water inrush of the tunnel, tunneling efficiency in quartz sandstone area and rock outburst while tunneling.
Research conclusions：Based on studying a large number of data and TBM construction cases, the main engineering geological problems in the area where the tunnel passed through were analyzed. Based on the analysis of TBM construction experiences at home and abroad, it was decided to adopt the open-type TBM for construction of the tunnel and to adopt the composite lining structure made up of bolt-shotcrete support+cast concrete lining as support system of tunnel instead of segment lining. It played an important role in construction of tunnel and could be as the reference to the similar projects in the future.
