摘　　要：利用ADINA计算程序，计算了单孔爆破半无限岩体内应变能的数值，得出了当抵抗线较小时，岩体内应变能分配均匀，有利于岩石破碎的结论。The ADINA program is used to calculate the strain energy in semi-indefinite rock massin single-hole blasting. From analysis of the rule of rock mass strain energy distribution varying withthe burden, it is concluded that rock mass strain energy is evenly distributed in case of smaller burdenwhich is good to rock mass breakage.
