摘　　要：根据砂土中爆炸在自由场产生的冲击波冲量对曲壁壁体的作用,并应用使结构破坏的能量准则,基于单个集中药包的药量公式,导出了利用填砂爆破解体曲壁结构时群药包的计算方法,可以作为曲壁结构填砂爆破实践群药包药量计算的重要参考依据。According to the effect of momentum of shock waves from explosions in sand-soil on the curved wall structures, the formulas of multi-charge weight for the filling-sand blasting were derived by means of criterion of energetic failure and based on the charge calculation of a single concentration charge in this paper, which will provide a good re/erence for calculating charge weight of multi-charge on the curved wall structures.
