通过对秦岭隧道混合片麻岩试件在不同温度下的单轴压缩蠕变试验，得出了不同温度下围岩的蠕变特性，提出可用以描述围岩蠕变特性的模型，并用试验数据确定出模型的参数
Based on the uniaxial compressive creep tests of mixed gneiss samples in Qinling tunnel at different temperatures, the creep characteristics of surrounding rock at different temperatures are obtained. A model which can describe the creep characteristics of surrounding rock is proposed. The experimental data Determine the model parameters
