中文摘要：
针对深部高应力软岩巷道围岩变形量大、变形速率快、持续时间长、流变性强的特点，采用Burgers流变模型，基于FLAC^3D进行了巷道围岩流变数值模拟研究，得到了巷道埋深．时间蠕变曲线、侧压力系数．时间蠕变曲线、弹性模量一时间蠕变曲线及黏滞系数．时间蠕变曲线，分析了它们对巷道围岩流变的影响规律。
英文摘要：
In connection with the characteristic of large deformation, high deformation rate, long duration and strong rheology in tunnel with soft rock under high pressure, the author has analyzed the regulation of their impact on the rheology of surrounding rock which is based on the software of FLAC^3D numerical simulation through the model of Burgers, and four creep curves can be got to show the relationship between time and depth, lateral pressure coefficient, elastic modulus and viscosity coefficient respectively.
