Summary:To get better prediction precision in settlement and deformation of the bridge piers and reduce errors in project monitoring practices, the learning algorithm and determination of network parameters of dynamic fuzzy neural network (DFNN) based on extended radial basis function neural networks (RBFNN) are introduced. In the selection of subsidence monitoring data from a bridge for the adaptive learning and training based on RBFNN and DFNN, the experimental results show that the prediction error of RBFNN is about 0.15 mm, while the DFNN is about 0.07 mm. The prediction precision of DFNN is better than RBFNN. Thus the advantages of dynamic fuzzy technology and neural network are confirmed in combining adaptive learning and training process.
