The BP Artificial Neural Network Model on Expressway Construction Phase Risk

摘要

According to the feature of expressway construction phase risk, an evaluation index system of expressway engineering construction phase risk was proposed. The BP artificial neural network model can be effectively used in engineering risk evaluation was built. The BP artificial neural network evaluation of the basic principles and process of engineering risk evaluation model, including the establishment of neural networks, learning and training, test results and case analysis, was explained.
