Blasting Vibration Test and Its Analysis in Demolition Blasting of Liaoning Provincial Gymnasium

摘要：

According to the analysis on demolition blasting vibration test of the Liaoning Provincial Gymnasium, we put forward that it is more reasonable to monitor three orthogonai vibration components at the same point and use the maximum value of three vector resultant point by point to reflect the strength in research for blasting vibration. The vibration in demolition blasting of such a large-scale gymnasium is caused by the impacting ground of the collapse of the buildings mainly, the strength of impacting is stronger than that of blasting. With the increase in height of buildings, vibration caused by blasting will increase in intensity. The conclusion mentioned above can be referenced in analysis on blasting vibration.
