混合片麻岩在一定温度下的蠕变试验研究

Creep Experiment Research of Surrounding Rock of Qinling Tunnel under Certain Temperature

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。

Through the uniaxial compression creep experiment of surrounding rock of Qinling tunnel at different temperature, the creep law of the surrounding rock at different temperature was obtained in this paper,the creep model which can describe the property of surrounding rock was derived ,and the parameters of the model were determined by using experiment data.
