摘　　要：叙述了采用积分算子解法时弹性解与粘弹性解之间的对应关系;具体求算出H-K体的蠕变核与松弛核;借助带有弹性支护的粘弹性围岩应力解析解,计算分析了支护结构上荷载以及围岩应力的分布形式与变化规律,对围岩的应力调整有了更深一步的认识,以便更好地为衬砌设计服务。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.
