摘要
Abstract
When grey GM(1,1) and Verhulst models are used to predict final settlement of dredger fill foundation reinforced by vacuum preloading method,the adopted modeling sequence affects directly the accuracy of prediction results. The settlement monitoring data on dredger fill foundation reinforcement are adopted to discuss the impact of the monitoring sequence length and the modeling sequence length on the accuracies of final settlement prediction values by applying the above two models. It is summarized the selection rule of modeling sequence for predicting final settlement with different models. The research results show that the above two models are able to predict final foundation settlement with the error less than 1.0%. In addition,grey GM(1,1)model is of better adaptability.关键词
