摘要
软土路基沉降的预测是高速公路建设的一个重要部分,目前预测方法越来越多,但由于路堤填筑受到自身或者外界因素影响,使得路堤处于间歇性填筑,因此选择合理科学的预测方法至关重要。在介绍软土沉降机理和Logistic曲线性质的基础上,结合西南地区遂(宁)—资(阳)—眉(山)高速公路遂宁至资阳段软土路基沉降预测工程实例,证明Logistic曲线在间歇性路堤填筑下软土路基沉降预测应用上具有科学合理性和适用性。
Prediction of soft foundation settlement is an important part in highway construction. Nowadays there are more and more predicting methods but, being subject to internal or external factors, the embankment filling is intermittent, hence it is crucial to choose a reasonable and scientific predicting way. Depending on the settlement mechanism and the characteristics of the Logistic Curve, this paper combined with the settlement predication for the soft foundation of Suining-Ziyang Section of Suining-Ziyang-Meishan Highway to prove the reasonability and operability of the Curve in the prediction.
