Abstract The propagation characteristics of seismic waves caused by underground explosion of penetrating weapons are more complex in the medium.In order to solve the problem of energy estimation after underground explosion of ground penetrating projectile, based on the modified Sadowski formula which reflects the elevation difference factor, the source energy calculation model of underground explosion under different topographic conditions was established in this paper.Then the explosion energy was obtained from the calculation results of the source model.In case 1, comparing the calculation results of the traditional source model (6) and the source model (12) in this paper, it was found that the accuracy of the source model proposed in this paper is much higher than that of the source model (6).In case 2, using the source model (13) in this paper, the calculated underground explosion energy has high accuracy when the measuring point is not in the same horizontal plane.The calculation results show that it is feasible to apply the theory of explosive vibration to calculate the explosion energy of ground penetrating weapons.

Key words： ground penetrating weapon seismic wave blasting vibration energy calculation modified formula
