摘要: 对空气冲击波在T型坑道内传播的到时规律及其影响因素进行了实验研究，在量纲一分析基础上建立了简化的工程模型。通过对实验数据拟合建立了可以对高能炸药在T型坑道内爆炸产生的空气冲击波到达时间进行预估的公式，利用该公式可以估算空气冲击波在T型坑道内的传播速度。

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
