摘　　要：以青岛地铁3号线一期工程土建03标太延区间下穿伊美尔整形医院为背景,对普通导爆管雷管和高精度延期导爆管雷管进行隧道爆破试验,爆破振速监测点均设在掌子面正上方。结果表明,使用高精度延期导爆管雷管在改善施工效率的同时,还能较好地控制爆破振速。Taking tunnel of Tai-Yan section underpass through Evercare Orthopedic Hospital,which is project of civil 03 bid of Phase 1 Project in Qingdao Metro(line 3),as an example,tunnel blasting tests were carried out on ordinary detonators and high-precision delay detonators.The monitoring points of blasting vibration velocity are located directly above the tunnel face.The results show that high-precision delay detonators can not only improve construction efficiency but also better control blasting vibration velocity.
