A Novel A-CNN Method for TBM Utilization Factor Estimation

Utilization factor is one of the most important performance indicators of TBM, which affects the construction period and cost of the tunnel. However, there are few models to evaluate the utilization factor based on geological conditions and operational parameters. In this paper, a novel A-CNN neural network architecture for TBM utilization factor estimation is proposed. Firstly, the input dimension is expanded by a full-connected neural network....
