摘要
针对杭甬高速公路深厚软土地基的沉降变形,以一维固结微分方程及实测沉降过程为基础,分析了一维固结沉降的预测模型,探讨了预测模型的辨识和滤波问题。通过分析实测沉降过程线,提出了分段沉降预测法。
Based on one-dimensional consolidation theory and the measured settlement curve, two models for ultimate settlement prediction of embankment are analyzed. Something is made on the identification of prediction models and data filter. A new model named piecewise prediction is proposed, which is proved to be reasonable.
