中文摘要:在软土地基上修筑路堤,最突出的问题是路堤的稳定与沉降。为掌握软土路堤在施工期中的变形动态,就必须进行动态观测和沉降预测,一方面保证路堤在施工中的安全与稳定,另一方面能正确预测工后沉降。而众多的预测方法给实际应用选择带来一定的困难,如何更科学合理地选择预测方法是工程技术人员面临的难题。就几种常用的曲线拟合预测方法的适用性进行分析,以期针对具体工程选取更为合适的预测方法,有效控制工后沉降并保证路堤施工和运营期的安全。

Assessment and Application of Common Prediction Methods for the Settlement of Embankment in Soft Soil
Abstract:The most prominent issue is stability and settlement in embankment construction in the soft soil, so dynamic observation and the settlement prediction is necessary. How to scientifically select the prediction method is a key point. The paper analyzes applicability of some common curve fitting prediction methods to show the more proper selection of prediction method in engineering, in order to effectively control post-construction settlement and guarantee the safety during the embankment construction and operation period.
