【摘要】 爆破震动对建(构)筑物的影响和危害较大。通过硐室爆破模拟试验,对不同布药结构产生的爆破震动强度进行了对比。业已发现,单或双条形药包产生的质点峰值振速均小于单或双集中药包的质点峰值振速;同时发现,质点峰值振速随单响药量的增加而增大,而振动频率随单响药量的增加而减小。本文对试验中发现的这些现象从理论上给出了解释。

【Abstract】 The blasting vibration has a great influence and harmfulness on constructions.Through simulated tests of chamber blasting,a comparison between the intensities of blasting vibrations from different charge layouts is made.It is found that the peak particle vibration velocities(PPV) induced by both single and dual linear charges are less than that of both single and dual concentration charge, and that the PPV increase with increased charge weight per delay interval while vibration frequency decrease with increased charge weight per delay interval.In this paper,these phenomena discovered in simulated tests are explained theoretically.
