| Abstract: | The paper introduces the correspondence principle between elastic solution and viscoelastic solution when adopting integral operator solution; calculates the creep kernel and relaxation kernel of H-K model specially; and analyzes the pressure on the supporting structure and the pattern of distribution and variation regularity of stresses in surrounding rock. The deepening understanding of stress adjustment in surrounding rock will be beneficial to liner design. |

| Keywords: | integral operator viscoelasticity loads on supporting structure time effect |
