摘　　要：爆破拆除钢筋混凝土结构物时,飞石控制是个重要的问题。工程中炸药量计算式 q=K·V 中的系数 K 的选择,很大程度上凭经验确定,这很可能导致炸药量过大、飞石失去控制。本文通过对实际工程数据的分析,得到 q=9。16×10^(-2)W^(0.90)关系式,并推荐此式作为钢筋混凝土爆破药量计算的参考式。It is an important consideration to control the amount and the distance of scattesing stones in blasting engineering to demolish reinforc- ed concrete.The fact that the coefficient K in the calculating formula of charge q=K.V.is usually selected by designers largely depending on their experienee may possibly cause the appearance of overcharging and the scatte- ring stones being out of centrol.Thus,in this paper,a new,simple and useful formula q=9.16×10^(-2)W^(0.90) will be given instead of the former after a group of data from practice having been analysed,which will be recomm- ended as a salty designation relationship in blasting engineering of reinforc- ed concrete demolition.
