【摘要】 对水压爆破时结构物临空面的冲击波反射情况进行了分析,提出了在不同的冲击波反射强度时的水压爆破药量计算公式,常用的水压爆破药量公式没有反映临空面的影响,所以该公式是对常用的水压爆破药量公式的改进,在实际工程中得到了成功应用。更多还原

【Abstract】 Controlledblasting technique have already used on demolition of old construction more and more. Hydraulic blasting is one of the techniques that is timesaving and laborsaving, convenience and more fast. After analysis the characteristics of water impact wave, this paper figure out pressure distribution of construction crosssection, bring forward a special dynamite amount formula which considerate the wave reflection, and contract this formula with common using calculation formula in engineering. Engineering practice in this paper also testify the formula’s applicability.更多还原
