摘要
从理论上探讨了平面应变条件下土产生非共轴变形特性的原因;结合试验结果分析了土的起始各向异性和应力状态变化对土的非共轴变形特性的影响.结果表明,应力方向的变化(即主应力轴旋转)是引起非共轴性的主要原因.
The origin causing the non-coaxial behavior of soil under plane strain conditions is theoretically discussed,and the influence of the initial anisotropy of soil and the change of stress states on the non-coaxial behavior of soil is also investigated. The investigation shows that the main reason for the non-coaxial behavior is the directional changes of stresses （ i. e. , rotation of principal stress axes）.
