摘要

以水布垭工区采石场开挖爆破对民房破坏影响范围鉴定为例,阐述了爆破振动影响范围的鉴定方法。根据建筑物的实际状况,确定爆破振动控制标准;在没有爆破振动监测资料的情况下,应按可能产生最大振动的不利条件选取爆破振动传播规律公式中的系数,以计算确定安全允许距离R安,并将爆破开挖边界线在水平投影面上向外扩大R安的距离,作为爆破振动影响分界线,分界线范围内为振动影响区,分界线范围外为安全区。
As an example of the damaging effect scope of houses identified caused by quarry blasting at Shuibuya Hydropower Project,the identification method and precautions are illustrated to be reference for similar projects.Make sure the control standards of blasting vibration according to the actual situation of the buildings;the coefficient which is in the formula of blasting vibration propagation should be chosen according to the disadvantages which is possible to produce in the case of there is no blasting vibration monitoring data,so to determine the allowed safety distance Rsafe,make the distance of blasting boundary line projected onto the horizontal plane outward extend Rsafe as the blasting vibration influence line,within the boundary is vibration influence zone,and outside is safety zone.
