摘　　要：随着工程技术的日益进步,对于爆破技术的施工效率和质量的要求越来越高,在达到爆破效果的同时如何尽可能地降低对周围岩体的损伤,值得进行深入研究。文章以丰满水电站保护层爆破试验为例,通过数值模拟技术,研究不同的炮孔垫层设计对孔底损伤的影响程度,得到最优化的爆破炮孔设计,以供类似工程借鉴。With the increasingly advanced engineering technology,there are higher requirements for the efficiency and quality of blasting technology.It is worth conducting in-depth research on how to minimize the damage to the surrounding rock mass while achieving the blasting effect.Taking the blasting test of the protection layer of Fengman Hydropower Station as an example,this paper uses numerical simulation technology to study the degree of influence of different blasting hole cushion layer designs on the bottom damage of the hole.It obtains the optimal blasting hole design for reference of similar projects.
