The section of No.3 Tunnel of Nanya Road passing beneath the botanical garden is very close to the cultural relic buildings and other buildings in the garden. Based on the project, the influence of blasting vibration on the cultural relic buildings is studied, and the blasting control measures are put forward through the FLAC 3D finite difference software. The results show that the corresponding blasting parameters are designed reasonably, which have a good effect on the blasting control.
