| Abstract: | This article,taking the test on ground settlement at the transition section between bridge and plain track in Tianjin-Qinhuangdao Passenger Dedicated Line for example,studies the prediction of ground settlement of the transition section between bridge and plain track with BP neural network and gray system method.The calculations prove that neural network and the gray system method offer a more accurate result in an easy and effective way;therefore it is of practical value in engineering and has a broad application prospect. |
