Analysis of lateral deformation of deep excavation based on back propagation neural network and fuzzy logical control

Based on the materials of practical survey on the real excavation displacement of underground engineering,an analytical model of nonlinear artificial neural network has been established. On the basis of above obtained result,the construction control plan can be predicted using fuzzy logical method. It is proved that the application of the ANN-fuzzy logic coupling model to the site construction control of the massif No.211 in Shanghai is successful. All these results have offered a new method for the construction control of underground engineering.
