Study Of Deformation Prediction In Baojin-Expressway Roadbed

The study of prediction of deformation about expressway soil roadbed is an important embranchment of soft soil problem. Firstly, the following aspects are studied about system of observation in original position: the selection ,disposal and installation of apparatus, the frequency and principle of observation.On the bases of combining actual data, the problem of prediction in roadbed settlement is resolved preferably by using grey model. On the premise of holding detailed datum in terra and design, the prophase prediction of roadbed deformation is carried out. And an ideal result is obtained by using calculation result to guiding the disposal with system of observation in original position.In the meanwhile, some shortcomings are found in informationization engineering. And finite element calculation and grey theory are applied, so a ideal effect is taken through the validation of practical engineering.
