The safety control standard of blasting vibration of high-voltage transmission tower is still not clear,which makes it difficult to guide the construction.Based on a highway tunnel under construction,this paper designs the blast hole network parameters for a tunnel with 200 kg explosive per round.The blast vibration signals are monitored near the tower foundation and statistically analyzed to study the bibration response characteristics of the high voltage tower and the attenuation law of the vibration signals.The results show that with the decrease of the distance to the blast source,the vector peak particle velocity of the tower foundation increases.The frequency band of vibration energy concentration tends to low frequency and the vibration frequency is obviously affected by the development degree of cracks in surrounding rock.The peak values of vibration velocity in the vertical direction are greater than those in the horizontal direction,so the vertical vibration damage of the foundation should be paid more attention to prevent any settlement of the medium.By adopting multi-delay initiation network and strictly controlling the maximum charge for lower delays,the damage effect of blasting vibration on the high voltage tower can be effectively weakened.Through data fitting,the attenuation formula of blast vibration in for this project is obtained.In this tunnel project,the blasting vibration velocity at the tower is controlled within 1.0 cm/s to ensure the safe operation of the high voltage transmission tower.Therefore,it is suggested that the competent authority of electric power and the law-making authority appropriately relax the control scope of blasting operations around the power facilities.
