摘要
本文以中村模型为基础,将粘性变形的概念引入了塑性区,并通过偏微分方程组的求解,首次得到了轴对称圆形巷道粘弹塑性的通解。
On the basis of the Nakamura Model, the concept of visco-deformation is introduced into the plastic field, and through the solution of partial differential equations the general solution for circular tumnels under axlesymmetrical loads is obtained for th first time
