Study on vibration peak values of charges simultaneous blasting seismic field and its application of cutting in slopes

Based on the principle of blasting seismic waves energy disperse in clay stone, the predominant direction of waves energy flowing and the relation between vibrations peek values and the distance from blasting sources, are researched, so that the rule of vibrations peak values strike is drawn, furthermore, the relation between slopes vibration intensity, and the angle between the slop plain and the envelope in which explosive charges exist, is obtained. By the regulation, blasting cutting in slop of Pan-Xi highway are redesigned, adjusting the dip angle of the envelope in which the explosives lie, to restraint the seismic vibration of the slope and to remain stableness of the slop.
