| Abstract: | 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. |

| Keywords: | tunnel high ground temperature deformation of surrounding rock visco-elastisity |
