| 摘 要： | 软土地基上高速公路工程建设中存在路堤临界高度的现象,根据国内外已有的文献资料全面总结了路堤临界高度的3种确定方法:实测资料确定法、理论公式计算法和离心模型试验法。在此基础上,根据某高速公路的大量实测数据,利用多元线性回归分析方法,得到了一个路堤临界高度计算的经验公式,探讨了软土地基硬壳层和软土层厚度与路堤临界高度之间的内在联系。

| Abstract: | The critical height generated during the embankment construction on soft ground is important to the behavior of embankment.Based on the systematic review of the existing literatures,it is concluded that there are three methods to evaluate critical height of embankment on soft ground,(1) the measured data analysis method,(2) theoretical formula method,and(3) centrifugal model test method.In addition,according to lots of settlement data in situ of certain experssway,multivariate linear regression model is adopted to analysis the relationships between critical height of embankment and thickness of soft clay or crust layer.An experiential formula is put forward to evaluate critical height of embankment on soft ground. |
