| Abstract: | In order to study the difference of shallow buried explosion effects between TNT and thermobaric explosive, shallow buried explosion experiments were carried out, and the differences between TNT and thermobaric explosive in crater morphology and surface air shock wave waveform were analyzed. The results show that the diameter, depth and volume of the crater produced by the thermobaric explosive are larger than that of TNT under the same working condition. When the depth of charge is 0.1 m and 0.3 m, the crater volume produced by the thermobaric explosive is 1.2 times and 2.3 times that of TNT. By comparing and analyzing the measured shock wave parameters, it is found that when the buried depth is 0.1 m and 0.3 m, the peak pressure of shock wave generated by warm pressed explosives at the measuring point with a proportional distance of 1 is 2.16 times and 1.41 times that of TNT, respectively; Within the research scope, the change of proportional distance and buried depth has little influence on the shock wave impulse attenuation of different types of charges, but has great influence on the attenuation rate. When the buried depth is increased from 0.1 m to 0.3 m, the impulse attenuation rate of both types of charges is nearly doubled. |
