摘要
试验证明,附加扰动对土样的影响不可忽略。由大量的试验结果得出了正常固结粘土强度和压缩特性随扰动程度的变化规律,以及土样贮存时间对土的强度特性的影响。
This paper deals with the influence of sampling disturbances on the soil behavior of normally consolidated clay. The test results show that, the effects of mechanical disturbances arising from sampling, transportation and testing can not be neglected. The properties of unconsolidated undrained test, reeonsolidated undrained test and consolidation test on disturbed samples are remarkably different from those on undisturbed samples. These phenomena become more pronounced with increasing disturbance and sample age.
