摘要
在姜洪伟(1995)所提出的软土各向异性弹塑性本构关系基础上,考虑类似于砂土的R-旋转试验条件,计算软土由于主应力轴旋转所产生的塑性变形,对不同中主应力比情况下的变形规律进行分析,解释忽略主应力轴旋转影响将使设计偏于不安全的原因。
Based on the anisortropic plastic stress-strin relationship of the soft clay presented by the first author, considering the R-rotation testing condition similiar to that of the sand, the plastic deformation caused by the rotation of the axis of the principal stresses is investigated and the deformation patterns under different ratio of the intermediate principal stresses are studied. In this way, the reason why the neglect of the effect of the rotation of the axis of the principal strsses may endanger the safety of the design may be interpreted.
