| Abstract: | Mountain tunnel construction method is commonly to use drilling and blasting method, the key technology is the smooth blasting. The level IV rock tunnel blasting excavation of the whole cross-section stress field and blasting vibration velocity field are analyzed by means of AUTODYN. According to the calculation results of numerical analysis, it is concluded that the corresponding optimization blasting design conclusion, so as to achieve rapid construction safety of late tunnel purpose, and for the similar tunnel engineering blasting construction to provide a good reference. |
