摘　　要：以某水电站改建工程为例,在阐述水电站进水口岩塞段实际情况的基础上,提出全排孔爆破施工方案应用的可行性,并对炮孔布置、孔深孔径、装药结构、起爆网路设置等施工过程进行分析探讨,最后根据所取得的施工监测数据进行了起爆施工期间空气冲击压力和水中冲击压力的分析,也验证了全排孔爆破施工法在该工程中的适用性,相关分析可作为水下工程岩塞爆破施工的借鉴参考。Taking the reconstruction project of a hydropower station as an example,based on the actual situation of the rock plug section of the water inlet of the hydropower station,this paper puts forward the feasibility of the application of the construction scheme of full row hole blasting,and analyzes and discusses the construction process of hole layout,hole depth aperture,charging structure,setting up of blasting network.Finally,the air impact pressure and water impact pressure are analyzed according to the construction monitoring data obtained.and the applicability of full row hole blasting construction method in this project is also verified.The correlation analysis can be used as a reference for rock plug blasting construction of underwater engineering.
