| Abstract: | According to basic theory of wave, a theoretical equation is derived for calculating transmission coefficent of blasting wave entering a structural face of a certain depth, and proved to be correct and reliable through ultra-dynamic strain tests of a similiar model. It is concluded that the stress transmission rate varies with stress wave′s incident angle. |

| Keywords: | blasting stress wave structural face transmittal coefficient ultra dynamic strain |
