摘要
为获得直坑道内爆炸冲击波的信号特征和传播规律,基于某基地已建成的爆炸坑道设施,通过进行多次TNT和温压药剂爆炸试验,并利用测试系统记录坑道内冲击波数据,分析了实测的冲击波数据和分类冲击波波形.得到了直坑道内爆炸冲击波传播的一般规律,和由实测数据拟合出的坑道内爆环境下不同药量的冲击波超压沿等截面直坑道传播的拟合方程,可为传感器选型及坑道内爆炸试验的威力评估提供依据.
Based on the explosion tunnel test facilities built by the some base, the purpose of this pa- per is to obtain signal characteristics and propagation law of blast wave overpressure. By the repeated- ly TNT and thermobaric explosive test, the wave overpressure data is recorded using the test system and data is analyzed using the software. Results and conclusions in the paper are that an engineering formula for predicting blast wave propagating inside the straight tunnel with constant cross-section is presented for detonations occurring outside the entrance tunnel by analyzing the measured blast wave- form and data and its propagation law. These researchs are available for selecting the sensors and evaluating the power in tunnel.
