摘要：沉降量和沉降速率控制是軟土地基上路堤工程設(shè)計的關(guān)鍵問題，由于固結(jié)理論的局限性和參數(shù)的不確定性，理論預(yù)測的精度較低，而基于現(xiàn)場實測數(shù)據(jù)的觀測法則顯示出了較高的精度。本文在Asaoka觀測法的基礎(chǔ)上,形成了一種軟土路基上分期施工時路堤沉降預(yù)測的方法，結(jié)合江蘇海相軟土上的高速公路工程進(jìn)行了沉降預(yù)測分析。
關(guān)鍵詞：沉降, 路堤, 觀測法, 分期施工, 江蘇海相軟土
0. 簡介
對于軟土地基上的路堤設(shè)計來說，沉降和穩(wěn)定性是需要考慮的兩個關(guān)鍵性因素?，F(xiàn)有的評估路堤穩(wěn)定性的方法基本上能滿足設(shè)計要求。因此，沉降便成了設(shè)計分析路堤長久性的關(guān)鍵參數(shù)。換句話說，對沉降的分析是路堤分析的最合適的方法。
軟土地基上路堤的沉降主要是由于路堤的固結(jié)和側(cè)向流動所引起的。對于軟土地基上的路堤，人們做了很多這方面的研究。

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.
