摘要

论文分析总结了工程爆破界对于爆破振动速度计算的经验公式。根据相似理论，推导了爆破振动速度计算的公式。研究结果发现，在地形、地质和使用炸药种类不变的情况下，爆破引起的地面振动速度与最大起爆药量Q、爆源距测点的直线距离R、以及爆破作用指数n有关。只有在集中药包、标准抛掷爆破条件下，爆破振动速度的计算公式，才适合于前苏联学者萨道夫斯基提出的经验公式。论文把深孔直列药包，假定为无数个等效集中药包，提出了深孔爆破的振动速度计算公式，并进行了工程实际应用

Abstract

In this paper，the calculation formula of blasting vibration velocity was analyzed and generalized. Based on similarity theory, the formula to estimate the blasting vibration velocity had been derived. In the same terrain, geological conditions and explosives，the ground vibration velocity depends on Maximum amount of primary explosive（Q），distance from Explosion source to measuring point（R） and blasting action index（n）. The calculation formula which was put forward by previous USSR scholar is useless unless standard throw blasting and concentrated cartridge. Finally, according to equivalence principle ，linear charge was assumed to be numerous equivalent concentrated charge，the equation of deep-hole blasting was derived，and it was successful in practical engineering applications
