摘　　要：炸药爆炸做功与岩体破碎耗能的耦合作用机理、炸药能量释放与爆炸裂纹扩展的精细控制原理,是岩石爆破基础理论需要解决的两个关键科学问题;“动静关系”研究是解决关键科学问题的重要途径之一.本文采用文献综述分析方法对2000年—2023年期间在中国知网数据库(CNKI)和科学引文索引数据库(WOS)收录的期刊论文进行了主题检索和分析,将岩石爆破“动静关系”研究划分为三个不同阶段:第Ⅰ阶段(2006年之前)、第Ⅱ阶段(2007年—2015年)和第Ⅲ阶段(2016年至今).确定了对“动静关系”研究有重要贡献的作者和研究机构,揭示了关键词及其共现关系,突出了研究的重点和趋势.通过对已有研究的系统梳理,结合作者团队已经开展的研究工作和成果,明确了新时期“动静关系”的研究方向,即爆炸应力波与爆生气体的动静能量分布与高效利用、考虑岩石爆破破裂真实物理过程的数值模拟算法、爆炸应力波与爆生气体动静破岩效果的量化调控.“动静关系”的深入研究将推动爆破工程从“经验主导”走向“理论指导”,从“粗放式”走向“精细化”.Blasting is a process in which the chemical energy of explosives is rapidly released,causing strong impact on the rock mass and achieving efficient rock fragmentation.The blasting stress wave and blasting gas generated by explosive detonation are the main driving forces for rock fragmentation.The high peak value and short duration of blasting stress wave are generally referred to as“dynamic action”,the low peak value and long duration of blasting gas are generally referred to as“quasi-static action”.The coupling mechanism between the work done by explosive detonation and the energy consumption of rock fragmentation,as well as the fine control principle of explosive energy release and blast crack propagation,are two key scientific problems that need to be solved in the fundamental theories of rock blasting.The study of“dynamic−static relationship”is one of the important ways to solve key scientific problems.Because of the complexity of the blasting process,traditional blasting design often relies on empirical formulas and field tests,posing problems such as low efficiency,high cost,and uncontrollable safety risk.Traditional designs often only focus on the final crushing effect but ignore the fine control of the blasting process.However,the study of dynamic–static relations has introduced a new approach to solution.This article uses a literature review analysis method to conduct a topic search and analysis of journal papers published in CNKI(China national knowledge infrastructure)and WOS(Science citation index-expanded database)in 2000–2023.The study of the dynamic–static relationship in rock blasting is divided into three different stages:Stages I(before 2006),Ⅱ(2007–2015),andⅢ(2016–present).Stage I focuses on the dynamic action of blasting stress waves,revealing the propagation mechanism of blasting stress waves and providing a scientific basis for related engineering applications.StageⅡstudies the crack propagation behavior under the action of blasting stress waves;many studies res
