【 摘 要 】

In this paper, a fuzzy evaluation-neural network tunnel construction safety and environmental evaluation model was constructed, according to the characteristics of tunnel construction. Firstly, the main characteristics of tunnel construction were analysed and the evaluation system was constructed. Then the weight of each set of construction factors was determined by using chromatography analysis method. Based on the realization of the system, the neural network was applied to train and test, and the model system was verified by engineering examples. The results show that the model system has better generalization ability and accurately evaluate the safety and environmental of tunnel construction.
