摘　　要：“隧道掘进水压爆破技术”于2002年12月18日通过了由重庆市科委组织的专家鉴定,认为该项技术为国内领先、国际先进。鉴定至今已过去近20年,经持续研究和应用,得到很大变化发展,以实际爆破效果和钻爆作业人员认可与否作为对隧道掘进水压爆破技术变化发展的评价标准,可以概括为3个发展阶段。重点介绍了炮孔装药结构改进变化发展提高及其取得的效果,尤其是第3阶段深受隧道掘进作业人员认可。现在推广隧道掘进水压爆破技术的队伍几乎全部采取第3阶段的炮孔装药结构,笔者对其原因作了较详细叙述。"Hydraulic blasting technology for tunnel excavation"passed the expert appraisal organized by Chongqing Science and Technology Commission on December 18,2002 and it is believed that this technology is domestically leading and internationally advanced.There have been great changes and developments after twenty years’continuous research and practical application since the appraisal.Taking the actual blasting effect and the approval rate of drilling and blasting operators as the criteria,its development can be divided into three stages.This article focuses on the changes of the blasthole charge structure and their application results.The third stage is especially welcomed among tunneling operators.Now all teams that promote hydraulic blasting technology in tunneling mainly adopt the third stage blasthole charge structure,and the reason is explained in detail in this article.
