A Study of Blast Vibration Effect and the Construction Safety

摘要

The principle of blasting earthquake effect is analyzed and it is pointed out that the explosion vibration has influence on structure and neighbouring people. The explosion vibration velocity is an important physical quantity that leads to structure damage, it response the quantity of earthquake wave energy. Through observation of the explosion earthquake at Tao Mine, the damping laws of the particle peak velocity, the vibration frequency, the longitudinal propogation velocity and its duration ect. have been obtained and the earthquake effects have been discussed. The author thinks that blast vibration safety regulation should be composed of blasting earthquake velocity and vibration frequency.
