| Abstract: | Based on the practical project,the key points for blasting and vibration-reduction design of new highway tunnel overpassing water delivery tunnel have been introduced and 3D numerical simulation analysis has been carried out in the whole construction process.Research results show that water delivery tunnel is stable under the whole construction process and the construction of highway tunnel is good for mechanical behavior of water delivery tunnel.The research results can provide references for the design of similar project. |
| Keywords: | Tunnel Mechanical behavior Numerical simulation Control blasting Vibration-reduction |
