摘要(Abstract)：

胶州湾服务隧道明挖段爆破开挖工程周边环境复杂,由于所在位置处于某军营地院内,需严格控制爆破飞石和爆破振动效应,爆破设计和施工难度较大。采用主爆孔逐孔起爆延时爆破技术,并结合预裂爆破达到了预期效果。介绍了该复杂环境下主爆孔和预裂孔的爆破参数选取及起爆网路设计,并对爆破效果进行了分析,可为同类工程提供借鉴。
The surrounding environment of open excavation section in Jiaozhou bay tunnel was complex.The engineering was required to control the blasting vibration and flying rocks strictly,because the location was in the camp,blasting design and construction were more difficult.Delay blasting technology of main blastholes was used hole by hole,combined with presplitting blasting,the desired results were reached.The blasting parameters and initiation network design of the main blastholes and presplit holes were introduced,and blasting effect was analyzed.It could provide a reference for similar projects.
