摘要

路堤或堤坝工程中土工合成材料加固软土地基得到广泛应用，但其计算方法仍有不足之处。从极限分析的角度来研究，引入滑移线法来改进极限分析上限法，推导出一种新的地基极限分析方法，并基于推导的极限承载力计算公式，把路堤破坏宽度作为变量，求解出路堤极限高度。工程实例对比分析表明，路堤极限高度计算结果与实测结果相差不大。其研究结论为软土地基路堤设计提供了一个新的和有效的方法。

Abstract

In embankment projects

the geosynthetics have been widely applied to reinforcing their soft grounds; but the calculation methods still have some shortcomings. The paper made a study from the aspect of limit analysis theory; the slip line method was adopted to improve the upper-bound theorem of limit analysis and deduced a new limit analysis method of ground. When the destructive width of embankment was regarded as a variable

this paper solved the ultimate height of the embankment based on the deduced formulas. The calculated results of the ultimate height agreed well with the measured ones

as the comparison and analysis of project cases showed. The results provide a new efficient way for the design of soft ground embankments.
