Research for Settlement Prediction on the Based of Neural Network and ADINA

It is important geotechnical problem to consolidation of soft soil foundation. Three-dimensional finite element model is established on the based of Biot consolidation theory, the model is loaded and calculated on the based of considering lateral deformation and spatial seepage, elastic-plasticity character of soil, construction stage loading progress etc. ANN has the advantages of self-organizing, adaptive identifying, self-studying and being tolerant towards errors, and is trained and tested by the data sample to back analysis parameter of soft soil foundation, and then the settlement prediction model is established by finite element method, prediction data compare with measured data, the result indicate that the model can give a precise forecast and is rationality. The method can provide the reference for the construction.
