摘要
根据秦岭隧道围岩在不同温度下的蠕变试验结果，用粘弹性理论对处于深埋高地热条件下的隧道围岩粘弹性变形进行了定量的分析，指出了高温与常温条件下围岩变形存在的差异及高温条件下可能带来的问题，对及早预防高地热引起的灾害有积极的作用。
According to creep test results of surrounding rock of Qinling tunnel under different temperatures, visco-elastical deformation of surrounding rock at great depth and high ground temperature is analysed quantitatively using visco-elastical theory. Existing difference of surrounding rock deformation between normal and high temperature and problems at high tempetature are pointed out. This has positive effect for preventing early disaster caused by high ground temperature.
