Analysis on Damage Effect of EPW Blasting in Certain Deepness of Blindage

摘要

In order to study the influence of charge weight and blast position on damage effect of EPW (Earth Penetrating Weapon), theoretic analysis was combined with experiment data, the model of volume of funnel pit formed by blast was set up based on supposing that the warhead was instantaneous spherical explosion and the fragments' destructive effect could be neglected, then the model was discussed in detail. The results are helpful to the launch and control of the EPW and have reference value for the building of contravallation and underground blindage.
