| 摘 要： | 为分析不同测试单位给出的直剪试验固结快剪强度指标有差异的原因，通过原状土样的直剪固结快剪对比试验，研究预压固结时间、剪切仪器和剪切速率对直剪固结快剪强度指标的影响，并对影响因素进行分析。结果表明，剪切速率是引起直剪固结快剪强度指标差异的主要原因。

| Abstract: | For analyzing the reason of variation in the strength indexes of the shear strength indexes provided by different test department, the influence of the preloaded-consolidated time, shear apparatus and shear rate can be researched on the shear strength indexes through the comparative consolidation quick direct test on the undisturbed soil sample. Moreover, the influence factors are analyzed. The results indicate that the shear rate is the main reason of variation in the strength indexes of the shear strength indexes. |
