VISCO-ELASTICAL ANALYSIS OF SURROUNDING ROCK DEFORMATION OF QINLING TUNNEL AT GREAT DEPTH AND HIGH GROUND TEMPERATURE
秦岭隧道在深埋高地热条件下围岩变形的粘弹性分析

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.
