摘要(Abstract):
本文在探讨工程爆破物理过程的基础上,分析了在何种条件下几何相似律与能量准则成立的条件。对硐室爆破、深孔爆破及水下爆破都分别作出了相应的爆破模型律,并给出了在实验室内做模型试验时选择模型材料的方法。
Based on the analysis of physical processes of engineering blas-ting,the conditions while geometrical similarity law and energy criterion holdwere illustrated.Modelings of chamber blasting,longhole blasting and under-water blasting were given. A method for selection of modeling materials inlab modeling tests was given.
