| 摘 要： | 针对广州南沙原状软土进行了一系列室内试验研究,包括三轴压缩试验、三轴蠕变试验和一维固结试验,系统地探讨了软土的蠕变变形特性。结果表明:软土的蠕变特性与多种因素有关,包括土体的初始固结度、土层排水条件、加荷比等;次固结系数与固结压力的关系取决于土体的先期固结压力和试验中的加荷比。

| Abstract: | Based on a series of laboratory tests with undisturbed samples obtained from Nansha of Guangzhou, including triaxial compression test, triaxial creep test and one dimensional compression test, creep deformation characteristics of soft soils were researched. It was shown that there were many factors impacting on the creep characteristics of soils, such as the initial degree of consolidation, drainage condition, load ratios and so on; and the relationship between coefficient of secondary consolidation and consolidation pressure depended on preconsoildation pressure and load ratios in the test. |
