| 摘 要： | 通过各向等压固结轴向加载三轴压缩试验和等应力比固结侧向卸载三轴试验获得的土体变形参数，对一个工程实例进行了有限元分析，分析结果表明：等应力比固结侧向卸载三轴试验获得的土体变形参数的计算结果与实测资料比较吻合。故为了准确地分析土体在各种工程荷载作用下的变形情况，有必要在试验时尽可能模拟土体的实际加载路径。

| Abstract: | Laboratory tests at two different stress paths have been carried out to analyze the influence of stress paths on soil's deformation characteristics. The conclusion obtained from the finite element analysis shows that the stress paths have great influence on soil's deformation characteristics. For accurate estimation of the soil's deformation at actual stress paths and consolidation stress ratios, laboratory tests should be conducted similar with real conditions. |
