| Abstract: | Based on analyzing the factors which caused ground deformation during shield constructing,the relation between displacement and soil conditions,excavate parameters of shied machine is built with the method of artificial neural network,and the sample data can be obtained from trial excavate phase of the shield tunnel.Then some critical factors are analyzed for this prediction technique,and some suggestions are given.At last,a simple back propagation network forecast model is used for surface settlement prediction in shield tunneling of Shenzhen metro |
