摘要
在试验结果的基础上,采用轴对称有限元方法对大型直剪仪的尺寸效应进行分析。结果表明,剪力盒壁摩擦力将会影响试验土样中的应力分布和剪切面上的正压应力值。在利用大型直剪仪进行试验时,应尽可能排除摩擦力的影响。
Based on the results of tests, the effects of the size of large direct shear apparatus are analysed through axial symmetrical finite element method. The results show that the frictions caused by the wall of shear box will influence the distributions of stresses in specimens and the normal pressure stresses on the shear plane. The influences of frictions should be eliminated during tests through large direct shear apparatus.
