the Formula of Intermediate principal stress at failure of Mohr-Coulomb material in plane strain state was obtained by analyzing the Lode angle parameter and the general Mises yield criterion matched Mohr-Coulomb yield criterion in plane strain state
which helps to study the strain-stress of geotechnical materials and the strength effect of intermediate principal stress and also helps to modify Mohr-Coulomb yield criterion. Second
the relation of intermediate principal stress at failure in plane strain state between Mohr-Coulomb material and SMP material is put forward. Finally
a foundation under plane strain condition was analyzed by FEM; and the computational results shows that the formula is correct.
