Abstract:
In order to estimate the settlement of soft clay foundation embankment, taking Verhulst curve as regression analysis model, and the model is calculated with threestage calculation method and least squares fitting method to predict the settlement. The time factor index of Verhulst curve model is also discussed. The prediction datum of Verhulst curve method, Hyperbola method and Xingye method are compared with the ones of actual measurement. It shows that the prediction results of three methods are very close to the actual settlements, and the final prediction result of Verhulst curve method is bigger than the ones of Hyperbola method and Xingye method. Adopting Verhulst curve does not need to confirm initiative time and settlement of reference point, it can reduce the influence of peoples subjective factors, and the bigger prediction value means more safety in project. 3 tabs, 4 figs, 10 refs.
