A study on the evaluation of influences of blasting vibration on buildings

Based on data observed in the blasting vibration test of the K107+157~268 road slope and K107+730~816 road slope of Hurongxie Expressway, an empirical formula for the blast vibration is obtained after the treatment of mathematical regression analysis. The vibration velocity of buildings at the different distance is calculated with this formula. With reference to the permissible safety vibration velocity standards of different buildings during blast, the safety condition of civil buildings near the blasting area is evaluated. Safety distances of the blasting vibration for different buildings are also given. All these help to ensure the blasting engineering goes smoothly. The research achievements of the paper can also serve as reference to similar projects.
