铁路隧道近距离下穿楼房控制爆破试验研究

结合内水－昆明铁路盐津1号隧道下穿楼房的实际情况，借助试爆和振动监测手段，对铁路隧道近距离下穿楼房应采用的爆破方法进行了研究。结果表明，在现场进行爆破设计所得的爆破参数是合理的，有利于近接隧道工程的成功修建；近接地下工程的修建中，在重难点工程施工前，现场进行爆破试验和振动监测是确保工程成功修建的有效手段；干扰减振爆破技术有着巨大的利用空间，随着爆破技术及爆破器材的发展，在将来的控制爆破中将发挥不可估量的作用。

Controlled blasting experimental research of railway tunnel under through buildings closely

Combining the practical situation of Neijiang to Kunming Railway Yanjin Tunnel #1 under through the buildings, by the means of trial blasting and vibrancy monitoring, blasting methods which should be used was researched for the railway tunnel under through the buildings closely. The result shows that they the blasting parameters which gained by blasting design in site are reasonable; propitious to the buildings of closely tunnel construction successful; during the construction of closely underground engineering, before the major and difficult construction, blasting test and vibration vibrancy monitoring were the effective methods to ensure the construction successful to build; the disturbance damping blasting technique has wide utilization space; with the development of blasting technique and blasting equipments, it would display imponderable effects in controlled blasting in future.
