摘要:
为了研究水下延时爆破对地表振动的影响，在某一小水池中，采用不同延时药包组合引起地表振动，对其进行测试。试验中各组合总药量相同，药包个数不同，对地面产生的振动速度和主振频率采用UBOX-5016型振动自记仪进行测试和分析。研究并发现毫秒延时爆破能有效降低爆破振动，通过选出的较优延时组合，初步估计合理的延时间隔为25～50 ms。
Abstract:
Ground vibration tests at different charge delay intervals were conducted in a small pool to study the impact of underwater delay blasting on the vibration of ground surface. During the experiment, the charge number was various for each group at a constant charge quantity in total. The ground vibration velocities and main frequencies were tested and analyzed by UBOX5016 blasting vibration recorder. The study shows that millisecond delay blasting can effectively reduce the blasting vibration. The reasonable delay interval was preliminarily estimated to be 2550ms at optimized charge delay interval.
