Abstract:

To eliminate the effect of blasting vibration on subway construction and the surrounding structures in shallow buried tunnel, several vibration monitoring tests were conducted on the Zhongyinggong-Xiaoxigou segment of Xinjiang Urumqi Line 1 subway tunnel surface. The vibration velocity decreases gradually. By HHT transform analysis of blasting vibration signal, it is concluded that the vibration energy generated by blasting is mainly distributed in the time period of 0~1.5 s and low frequency band of 0~50 Hz. Dividing cut holes into several segments can significantly reduce the surface vertical vibration velocity, and it effectively control the impact of the tunnel blasting construction on the surrounding structures. © 2018, Editorial Department of Transaction of Beijing Institute of Technology.
