中文摘要：

应用快速拉格朗日有限差分法（Fast Lagrangian Analysis of Continua）,分析不同压实度对黏性土与粉性土中高路堤的沉降变形的影响,从而确定合理的压实标准。针对拟定的4种路基压实标准进行数值分析,计算不同高度的路基的沉降变形,并提出路基沉降的拟合曲线公式。结果表明,对两种土质的路堤而言,在不同路基压实标准的条件下,路堤高度对路基变形的影响呈抛物线形关系,通过提出的回归公式,就可估出变形达到稳定时路堤的沉降量。不同的路堤填高应提出不同的路基压实标准,而且黏性土与粉性土应给出不同的压实标准。

英文摘要：

The finite difference method of Fast Lagrangian Analysis of Continua is used to analyze the influence of the different compaction degree on the middle and high embankment settlement in order to determine the logical program of compaction degree. Considering the four programs of compacting criteria, the embankment settlement in the different height is calculated, and the equations of the fitting curves are put forward. The results indicate that in view to two soil behaviors and the four programs of compacting criteria, the influence of the height of the embankment to the settlement demonstrates the parabola form, and the settlement could be estimated through the equations of the fitting curves. And there should be different compaction degree for different high embankment and different soil behaviors.
