| Abstract: Risk assessment of railway construction is an important part of railway construction project. In view of shortcomings in traditional risk assessment methods for railway construction, this paper builds an interactive variable BP (Back Propagation) neural network model based on particle swarm optimization and applies it to the risk assessment of railway construction in European countries. The evaluation results of the training set and the veri cation set all show that this model can effectively predict and evaluate the risk level of railway construction and has a high evaluation accuracy. |
