TBM tunnel construction of pumping and storage project has ultra small excavation section,complex and changeable geological conditions,multi fault fracture zone and surrounding rock deformation,high ground stress,rock burst,ultra small turning radius,large section slope and long length,and intensive mechanical operation.In view of the difficulties in complex geological prediction,tunnel support,and adjustment of tunneling parameters for different strata during the tunneling of drainage gallery tunnel,exploratory tunnel,traffic pilot tunnel,etc.,the technical framework of TBM key parameter intelligent tunneling system is designed,and the development threshold is reduced by adopting the low no code mode.The system achieves a low coupling degree through modular development.On this basis,the model from different algorithm developers is integrated in the way that the algorithm model and the system software belong to different services,and the rapid integration of the system software and the algorithm model is realized,which is used for the prediction and control of key parameters in the TBM intelligent tunneling process.The intelligent construction process of TBM tunnel is studied and analyzed,and a set of TBM intelligent tunneling system technology for pumping and storage projects is formed.It has been successfully applied to Zhejiang Qujiang pumped storage project and Zhejiang Yongjia pumped storage project,forming a set of intelligent construction methods that meet the TBM Construction of pumping and storage projects.
