Problems solved by technology

[0005] (1) Rock slag, as the product of TBM rock-machine interaction, has very important guiding value for TBM excavation, but the information contained in slag has not been fully valued and utilized in the current optimization of main operating parameters of TBM ;
[0006] (2) In terms of tool consumption research, the existing research is more concerned with the impact of rock mass parameters on hob life, and rarely considers the impact of TBM as the main operating parameter on it;
[0007] (3) In the existing studies, a single TBM main control parameter is mainly used as the optimization target, and multiple target parameters are rarely combined for optimization, and the main operating parameters of the TBM are not optimized by taking the tunneling speed and tool consumption as constraints at the same time
