Abstract: 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.

Key words: railway tunnel, closely, blasting parameter, vibration monitoring, disturbance damping
