Claim 10:
11. The construction method of rock burst prewarning protection system in non-contact tunnel construction according to claim 6, wherein in Step III, the rock core is divided equally into multiple samples after acquiring the rock core, and the isothermal triaxial tests is conducted under different environment temperatures for giving different base temperatures to rock core, so as to obtain the correlation between the temperature change rate and deformation rate of the same type of rock core before rock burst at different base temperatures, which means to find that under which kind of the temperature change acceleration the rock core produces a higher deformation acceleration further to form the rock burst, taking this correlation as a rock burst criterion in the “surrounding rock mechanical parameter-rock burst critical deformation-rock burst critical temperature” database and the rock burst prewarning model.
