Elastoplastic Analysis on Circular Tunnels Surrounding Rock under Asymmetry Load

Abstract:

The analytic solution for circular tunnel under asymmetry load usually uses C-M criterion, and the finite element calculation usually uses D-P criterion. In this paper, the complex variable function method is employed to do an elastoplastic analysis based on Tresca Criterion, obtained the stress and plastic radius in elastoplastic region. The result shows that extent of stress in elastic region is no longer match the Krisch solution. The solution is in good agreement with Sun GZ’s solution and finite element simulation based on ANSYS, which can be used in simple elastoplastic analysis of surrounding rock instead of finite element method.
