| 摘 要： | 饱和软土压缩试验时,经常出现压缩曲线“反常”、压缩系数“倒大”的现象。它是土的原始结构发生破坏前后的不同压缩性的客观反映。饱和软土的结构力很微弱,唯质量好的原状土才能见到这种“反常”。应从成孔、取样、测试及资料整理等多个环节保证其工程意义。

| Abstract: | "Abnormal" phenomena of compressive curve and "inverse big" of coefficient if compressibility often occur when the compression test of satured soft soil is being done. It is the objective reflections of different compressibilities before and after destruction of original texture of the soil. The cohesion of the soft soil is very weak, this kind of "abnormal" only can be seen in the undisturbed soil of high quality. Therefore, it is should be from pore-forming, sampling and data arranging etc. links to ensure its engineering significane. |
