Abstract

The traditional method in solving geotechnical engineering problems can only come to the theoretical solutions. The triple-shear unified elasto-plastic constitutive model is proposed based on the triple-shear unified yield criterion, and the secondary development to ANSYS with the complicated practical engineering problems. The coincidence between the theoretical resolutions and the numerical resolutions for circular tunnels under the static pressure indicates that the proposed constitutive model and the subroutine codes are convincible. As an example, the slope stability is analyzed with the developed ANSYS software and come to the numerical resolutions. The results show the stability of landslide increases with the increase of the intermediate principal stress.
