Existing shield cutter selection method is mainly for experts to choose the appropriate cutterhead type on the basis of engineering hydrogeological conditions and their experience.
Cutterhead selection still needs to be identified by engineers refering to geological report and their experience.
The BP neural network algorithm adjusts its weight matrix using a large number of engineering samples, so individual error sample will not impact the selection
As shown in figure 6, the topology structure and number of spokes selected according to the geological parameters are identical with the actual engineering.
