Abstract

In order to investigate the temporal and spatial distribution of the stress wave in the soil produced by buried explosion, the ANSYS/AUTODYN software was employed for modelling and simulation, and the ground shock effect of explosion in soil was analyzed. Based on the relationship between the pressure and volumetric strain of Luoyang loess obtained by predecessors, the relationship between the pressure and density of the impact compaction in the SAND model was modified. The numerical model was validated by the test data, which were measured from the contact explosion and semi-buried explosion test in loess. Then, a total of 22 numerical simulation conditions were examined to study the influence of the scaled buried depth of the charge and the type of the explosive on the ground shock subzones. The results show that as the depth of the soil medium increases, the peak of induced ground shock decreases, while the peak of direct ground shock increases, until the peak of the pressure-time curve and the peak in the vertical stress-time curve finally merge into a single peak. According to the characteristics of the pressure and vertical stress at various depths, the stress wave field in soil can be divided into three subzones consisting of surface subzone, near-surface subzone and central subzone. With the increase of the scaled buried depth of the charge, the central subzone rapidly increases, the surface subzone rapidly decreases, and the near-surface subzone gradually increases from zero, when the scaled buried depth of the charge ranges from −0.05 m/kg^1/3 to 0.075 m/kg^1/3. The distribution of the ground shock subzones tends to be stable, when the scaled buried depth of the charge ranges from 0.1 m/kg^1/3 to 0.4 m/kg^1/3. The energy of the explosive coupling into the air and soil mediums is affected by the type of the explosive. In certain extent, the angle of the ground shock subzones is linearly related to the ratio of the air-blast overpressure impulse to the impulse of the direct ground shock stress.
