【Abstract】 The magnitude of the post-construction settlement is the key element subjected to design and construction of embankment on soft ground. The observational method based on field measurement has higher prediction accuracy and has become a more effective settlement prediction method. A new settlement prediction model is presented based on neural network theory in the paper. The case studies show the accordance of the predicted settlements by the proposed model with the measured data. The model has wide application foreground in expressway construction.更多还原
