摘要(Abstract)：

列举了一些常用的水压爆破药量计算公式 ,并对它们进行了简单的评述。通过分析国内外钢筋混凝土结构物水压爆破工程实例认识到 ,对于钢筋混凝土结构物水压爆破拆除 ,以常用公式中的药量系数k来估测爆破效果 ,往往出现较大的误差。作者推荐根据冲量及能量准则导出的公式 ,提出用破碎程度系数F=5Q/Q0 0 5作为爆破效果判断指标的观点。
In this paper,some common formulas for calculation of charge weight in water pressure blasting are cited and commented upon briefly It is considered by analyzing the engineering examples about water pressure blasting of reinforced concrete structures that,for demolition of reinforced concrete structures by water pressure blasting,a large error will arise as the charge coefficient k is used for estimation of a blasting result The author recommends the formula derived on the basis of the impulse energy rule and proposes a viewpoint of using the fragmentation factor F=5Q/Q 0 05  as an index for estimation of a blasting result
