| Abstract: |
| The experimental study adopts super dynamic strain system, and measures the blasting stress field of bundle-holes and equivalent hole with large diameter in concrete medium. The blasting wave characteristics of bundle-holes are analyzed through the measured waveforms. Furthermore, the paper describes the common and individual characteristics of bundle-holes’ blast waveform and previous classic blasting waveform and makes reasonable explanation to the waveforms. |
