摘要：沉降量和沉降速率控制是软土地基上路堤工程设计的关键问题，由于固结理论的局限性和参数的不确定性，理论预测的精度较低，而基于现场实测数据的观测法则显示出了较高的精度。本文在Asaoka观测法的基础上,形成了一种软土路基上分期施工时路堤沉降预测的方法，结合江苏海相软土上的高速公路工程进行了沉降预测分析。
关键词：沉降, 路堤, 观测法, 分期施工, 江苏海相软土
0. 简介
对于软土地基上的路堤设计来说，沉降和稳定性是需要考虑的两个关键性因素。现有的评估路堤稳定性的方法基本上能满足设计要求。因此，沉降便成了设计分析路堤长久性的关键参数。换句话说，对沉降的分析是路堤分析的最合适的方法。
软土地基上路堤的沉降主要是由于路堤的固结和侧向流动所引起的。对于软土地基上的路堤，人们做了很多这方面的研究。

methods based onfield measurement have indicated the promising results and become effective methods to predict the final settlement, while the uncertainties of parameters and theories limit significantly the accuracy of settlement estimation. This paper presents an observational method to predict the settlement performance of embankments with stage construction on soft ground based on Asaoka method. The case studies show the accordance of the predicting results with the field measured data. It is also given from the case study that the value of Eu / Cu ratio ranges from 50 to 100 for Jiangsu Marine clay and its actual coefficient of consolidation is almost one order of magnitude larger than the laboratory data.
