| Abstract: | Settlement prediction soft ground is one of the main concerns of the buildings.Based on some of the actual measured data on the settlement of buildings on soft ground,a power function curve linear regression-the gray theory combining nonlinear combination forecasting model was established.Theoretical analysis and practicel prediction indicate that the predictive value of the model is closer to the true value and the reliability of predictive outcomes are higher. |
