Abstract
The propagating regularity and its influencing matter of shock wave in a 90° bend tunnel were studied experimentally. On the basis of dimensional analysis, a simplified engineering model was built. Through collecting data gained from 4 experiments, a formula was proposed which can compute time of arrival in a 90° bend tunnel due to explosions from high explosive charges. This formula can also be used to compute velocity of shock in the 90° bend tunnel.
