Analysis of Ground Vibration Caused by Collapse of High Chimney Structures by Blasting

摘要

The ground vibration caused by a concentrated mass drop is analyzed. Through the measurement of ground vibration velocity of high chimney collapse by blasting the physical process of chimney collapse and attenuation of peak value of vibration velocity are given. The effect of the collapse of two tower buildings of world trade center in New York in 911 event is discussed.
