Study on Vibration Velocity Response of Surface Buildings to Blasting in Urban Tunnel |
| |
| Abstract: | Taking the double tunnel engineering in the interval from Tonghui Rd. to Railway Station South of Hangzhou Metro Line 5 as an example, the vibration velocity response of surface buildings to blasting excavation in urban tunnel engineering was depended to study the technology controlling blasting construction in under-crossing tunnel. The blasting tunneling in different distance to blasting source, cyclical footage and maximum charge quantity per one detonating period was studied with FLAC3D numerical simulation so that the rule of vibration velocity response of surface buildings under the action of blasting dynamic load was analyzed, and then verified by the data measured on site. |
