摘要(Abstract)：

在与既有隧道的间距很小的情况下进行新隧道的开挖爆破 ,应不影响线路的正常运营 ,为此必须采取一系列控制爆破震动的技术措施。本文论述了所采取的各种减震措施 ,其中包括开挖顺序、掏槽形式、循环进尺的确定 ,微差爆破的使用以及周边空孔的设置等。此外 ,还介绍了爆破震动监测
The excavation of a new tunnel with a small space to an existing railway tunnel shouldn't affect normal operation of the existing railway. For this reason, a series of technological measures for control of blasting vibration must be taken. In this paper, the adopted vibration reduction measures, including the determination of excavating sequence, cut mode, advance per round, the use of millisecond delay blasting and the set up of uncharged peripheral holes and others, are discussed. In addition, the monitoring of blasting vibration is introduced.
