Abstract

The invention provides a TBM operation parameter optimization method based on optimal tunneling speed and cutter consumption, and belongs to the technical field of tunnel boring machine construction.The TBM operation parameter optimization method based on optimal tunneling speed and cutter consumption comprises the following steps of obtaining rock mass parameter data; and taking the obtained rock mass parameter data as the input of a preset construction cost calculation model, and through interpolation fitting, obtaining cutterhead thrust and cutterhead torque when the construction cost is minimum, wherein the preset construction cost calculation model comprises a TBM tunneling speed prediction model and a TBM hob life prediction model. According to the TBM operation parameter optimization method based on optimal tunneling speed and cutter consumption, by combining the TBM tunneling speed prediction model and the hob life prediction model, the relation between a TBM main operation parameter and the construction cost is established, and therefore, the main operation parameter with the optimal construction cost are obtained.
