摘要
本文在室内模型试验与现场爆破漏斗试验基础上,着重论述了单个闭合状裂隙对单个球状药包爆破破碎效果的影响。指出,裂隙在降低介质的强度和降低爆炸气体的静载效应方面的影响是肯定的,而对动载效应,则不同条件下可能削弱也可能加强,并阐述了加强的条件和论据。
Based on the indoor model tests and field blasting crater tests, the paper discussed the influence of single closed fissure upon fragmentation effect of blasting with single spherical charge. It's positive that the fissure can weaken the strength of the medium and reduce static load effect of the detonating gas. However, the fissure can either weaken or strengthen the dynamic load effect, depending on different conditions.Conditions and theoretical basis for strengthening of dynamic load effect are described in the paper.
