Abstract
Because of the complexity of excavation engineering, it is very difficult to predict the displacement of retaining structure and the settlement of ground surface, and information construction is very important for an excavation engineering.A method for predicting displacement of retaining structure based on modified BP algorithm is used. The modified algorithm has higher convergence rate and thus improves the conventional one effectively. It is proved that prediction results agree with the measured ones very well, so displacement prediction by the modified BP algorithm is practicable. Finally, the relation between the displacement of retaining structure and the settlement of ground surface is analyzed.
