摘要
以弹性理论为基础，分析了混凝土中爆破漏斗的形成过程，研究表明无论是最大拉应力还是最大剪应力理论，药包的最小抵抗线都与药包半径成正比，随爆炸气体压力的增加而增加、随混凝土抗拉（或抗剪）强度的增加而减少。计算结果表明，对于标准爆破漏斗，按最大拉应力理论计算的炸药单耗与实际情况基本吻合。
Based on the elastic theory,the deforming process is analyzed about blasting crater in the concrete.The research indicates that the burden is proportional to the radius of charge based on both the tensile and shear theories.The calculated results show that the charge weight per unit volume based on the tensile theory is identical with the practical one of the standard blasting crater.
