本文对饱和粘性土不排水强度的确定精度及其与稳定性分析结果的关系进行了研究。就强度测定的准确性而言，从取样到试验的整个过程中的机械扰动的影响远远大于应力释放的影响，就无侧限抗压强度而言。分别考虑实测无侧限抗压强度的最大值、平均值和最小值，对粘性土的三个破坏实例进行了分析。分析结果表明，在考虑平均无侧限抗压强度沿深度分布的情况下，用σ u = 0分析可以合理地解释破坏的发生。
ABSTRACT The accuracy in determining the undrained strength of saturated cohesive soils and its sequence to the result of stability analysis are examined. As for the accuracy in determining the strength, the mechanical disturbance in the whole process from sampling to testing is found to have far greater influence than the effect of stress release in sampling, as far as the unconfined compression strength is concerned. Three case records of failure in cohesive soils are analyzed by considering respectively the maximum, average and minimum values of measured unconfined compression strength. Results of the analysis show that the occurrence of failure can be explained reasonably by the ϕu = 0 analysis, provided that the distribution of the average unconfined compression strength with depth is considered.
