摘要(Abstract)：

参照地震的抗震设计思想,并结合部分爆破工程实例分析,提出了适合城区大规模土岩频繁爆破以及高耸建筑物拆除爆破,应按建筑物设计地震烈度降2度来确定其爆破振动安全允许标准。
Referring to the idea of anti-seismic designing and the analysis of examples of some blasting projects,a safe and permitted standard of blasting vibration,suggesting that the 2 degree lower than the designed seismic intensity of construction should be suitable for the frequent urban massive blasting and tower buildings blasting demolition,was put forward.
