摘要
通过对“Ｖ”型切槽爆破断裂成缝机理的分析研究和模拟对比计算， 提出了切槽尖端动态应力集中和“Ｖ”型切槽尖端附近区域裂缝生成抑制联合作用的断裂成缝机理。
The Fracturing mechanism under combined action of the dynamic stress concentration on notch tip and the restraint of crack growth in areas near dose to “V” shape notch tip is presented, according to theoretical analysis and computerized simulation of “V” shape notching blasting.
