Abstract

Abstract

The propagating regularity and influencing factor of shock wave in a T-shaped tunnel were studied experimentally. On the basis of nondimensional analysis, a simplified engineering model was established. By collecting data gained from 4 experiments, a formula was propose. This formula can be used to calculate arrival time and propagation velocity of shock wave in a T-shaped tunnel due to explosion from high explosive charges
