In order to analyze the mitigating effect of water mist on the explosive shock wave inside a cabin,a series of TNT explosion experiments in the center of a cabin were carried out,from which the wall pressure and quasi-static pressure inside the cabin in different cases with and without water mist were measured. Results show that water mist truly has an evident effect on attenuating the overpressure peak of blast wave and the quasi-static pressure. In the experiment of 27. 5 g TNT exploding in cabin,the attenuation rate of initial shock wave overpressure is 26. 47%,the attenuation rate of secondary reflected wave pressure is is about 27. 27%,and the attenuation rate of quasi-static pressure is about 31. 82%. For the same water mist density,the mitigating effect of water mist on the blast wave decreases with the increase in TNT charge.
