【Abstract】 An empirical formula of blasting vibration velocity attenuation is proposed in this paper by field test in the Yangtze River Taiziji Waterway dredging blasting project.The safety criteria of the blasting velocity and the max allowed explosive under different conditions are presented.The effect of the underwater drilling blasting is assessed based on the measured data so as to ensure the safety of the Yangtze River levee.更多还原
