  • Calcareous sand is widely distributed in coastal areas, and its engineering and mechanical properties are significantly different from terrestrial sands. To study the blast wave propagation in calcareous sand, a series of explosion tests with various charge weights on the ground surface were carried out in calcareous sand and silica sand. Pressure time-history curves at positions directly below the explosion center were measured. The propagation laws of two kinds of sands were investigated, including peak pressure, wave velocities of elastic and plastic waves, the rise time of pressure and size of cater. The results show that the blast wave propagation in calcareous sand differs from that in silica sand. Tests under 0.2 kg and 0.8 kg charge weight were conducted twice. And the results show that the explosion experiment is repeatable. Cater produced by the surface explosion in calcareous sand has a smaller size than in silica sand, and the shape of the cater is two-tier concentric circles, one of which is small in diameter and large in depth, and the other is large in diameter and small in depth. The elastic velocity in calcareous sand is 236 m/s to 300 m/s, and that in silica sand is 218 m/s to 337 m/s, while the elastic wave and plastic wave velocity increase with the increase of the explosive charge. The rise time of the blast wave pressure in calcareous sand increases with the increase of scaled distance. In silica sand, rise time does not change with the scaled distance and is much smaller than that in calcareous sand. The measured peak pressures are fitted by using a power function of scaled distance. The attenuation laws of peak pressure in calcareous sand and silica sand are derived. The attenuation coefficient of calcareous sand with low moisture content is 2.86, and 2.79 for silica sand.
