| 摘 要： | 针对滨海公路软土路基的工程地质特征,以深圳市滨海大道试验研究为依托,探讨了该类地区软土路基变形机理及其沉降发展规律,并通过对各种沉降预测模型的对比分析,结合5种常用的成长模型,提出了滨海公路软土路基变权重组合S型成长模型。最后,以该模型对依托工程进行了沉降预测,结果表明该模型预测效果较好,适用于该类地区路基工后沉降量预测,对实际工程具有一定的实用价值。

| Abstract: | According to the geologic characteristics of soft clay embankment of coastal road and based on the in-situ test of coastal road in Shenzhen,the deformation mechanism and settlement developing regularity were discussed.The variable-weight combination forecasting model is proposed based on comparisons of various forecasting models and five growth models.In the end,compared the predicted values by the present method with the measured data from the in-situ test shows good agreement,and the method adopted in settlement forecast of Soft clay embankment in coastal road may be adopted in engineering practice. |
