The Vibration Velocity and Vibration Level of Near-field Blasting Vibration in an Urban Blasting Site

근접장 발파진동에서 진동속도와 진동레벨

To compare blasting vibration at blasting construction field in urban area, the vibration level (dB(V)) and vibration velocity (cm/sec) on the ground and the structure of buildings due to the differences of the measuring sites from the blasting source is investigated and the difference between the measured vertical vibration level and the calculated vibration level by using vibration velocity PVS and the correlation between vibration velocity and vibration level and is studied in the thesis.
