地震效应及安全研究

The study of blast vibration effect and safety

分析了爆破地震效应原理,指出爆破振动速度是导致结构破坏的一个重要物理量,他可使建筑物的正常工作受到影响,同时,对附近居民产生影响。结合桃矿爆破地震观测,研究了爆破地震质点峰值振速衰减规律、振动频率、纵波速度和振动持续时间等地震效应及其安全问题。

The principle of blasting earthquake effect is analtzed and it is pointed out that the explosion vibration velocity is an important quantity that leads to structure damage.At the same time ,blasting earthquakes have influence on neighbouring people.Through observation of the explosion earthquake at Tao Mine,the damping laws of the particple peak velocity,the vibration frequency,the longitudinal propogation velocity and its duration ect.earthquake effects and safty issues are discussed.
