【摘要】 本文将爆炸应力波以预裂缝高度将其分成上部应力波和底部应力波, 分别应用节理刚度模型和应力波理论解释了预裂缝对其减弱和阻隔作用, 从理论上说明了预裂爆破的减震机理, 并进一步讨论了预裂缝宽度的影响和减震效果分析。更多还原

【Abstract】 The blaing ress wave is separated into the top and bottom wave by the high of the pre-splitting slot.With the iffness model and the theory of ress wave,the shock absorption is illuminated by the slots and its mechanism of pre-splitting is explained in theory.And more,the infection of the width of slot and the effect of absorption are discussed.更多还原
