摘要(Abstract)：

介绍复杂环境下青岛航母基地048工程道路扩建项目电缆隧道的控制爆破。分为严格控制爆破区、控制爆破区及一般地段沟槽爆破区,分别实施不同的爆破方案。结合现场测振,采用潜孔钻钻孔,分段毫秒延时爆破等技术措施,达到了预期爆破效果,保证了周边建筑物、管道的安全,确保了工期。
The cable tunnel controlled blasting of 048road expansion project of the aircrafts carrier base in Qingdao in complex environment was introduced.It was divided into strictly controlled blasting area, controlled blasting area and general section groove blasting area,each was implemented by different scheme.Combining with on-site vibration measurement,using down-the-hole drill drilling,sub millisecond delay blasting and other technology measures,the desired blasting effect was achieved,the safety of the surrounding buildings and pipelines was guaranteed,and the duration ensured.
