通过对宁波粉质粘土固结快剪试验结果的分析可以看出,剪切速率对宁波粉质粘土固结快剪的摩擦角影响很大,剪切速率较大时,摩擦角较小;剪切速率相对较小时,摩擦角相对较大。对剪切速率比较敏感的粉质粘土在做固结快剪试验时,应采用较大的剪切速率。

It can be seen from the analyses of the results of the consolidated quick shear tests of silty clay in Ningbo that the shear rate influenced a lot the frictional angle of the silty clay in consolidated quick shear tests.When the shear rate was higher,the frictional angle was smaller;and when the shear rate was relatively small,the frictional angle was larger.For silty clay more sensitive to the shear rate,higher shear rate should be adopted when the silty clay is subject to the consolidated quick shear tests.
