Abstract: 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).

Key words: non-coaxial behavior； angle of non-coaxiality； stress state； anisotroppy； plane strain；
