摘要
提出了4种新的拟合函数对邵怀高速公路 K79+500断面软土地基的残余沉降进行拟合和预测,经过对比分析,Morgan Mercer Florin 和韦布尔模型能比较好拟合路基的残余沉降曲线,所预测200d 后的残余沉降分别为10.5cm 和11.6cm。并将预测结果与数字计算结果进行比较,预测结果与数值计算结果比较接近,说明了 Morgan Mercer Florin 和韦布尔模型预测沉降的可行性。
Four kind of functions for the foundation settlement simulation and forecasting model were presented, and the new settlement simulation and forecasting models were respectively used to forecast the remainder settlement of K79 ＋ 500 embankment in Shaohuai highway. Through the comparison, Morgan Mercer Flori and Webull functions were the optimal model for the remainder settlement forecasting, and the settlement forecasting values of these models were 19.5cm and 18.6cm respectively. Compared the numerical calculation values with these forecasting values, there was a good agreement between the numerical calculation values and the forecasting values, which suggest the Morgan Mercer Flori and Webull function model＇s feasibility.
