Aimed at the question that how to increase coefficient of utilization of blasting energy in the plane charge blasting, the dynamic simulation of propagation process in the plane charge blasting had been dynamically simulated based on the finite element software ANSYS/LS-DYNA. From the stress nephogram and velocity-time curves, the article had explored distribution of explosion stress and vibration velocity affected by plane charge blasting directions. Through the comparison between blasting curves in the positive and negative directions, and analyzing the distribution effects of ground structure vibration based on the blasting earthquake response spectrum after the plane charge blast, and a conclusion that blasting energy distribution could be controlled by the blasting direction in the plane charge blasting was drew.
