(一)问题的提出大爆破产生的爆破地震效应是炸药在土岩中爆破时振动区域内所产生的现象。即炸药在爆轰中释放出的炸药能的一小部分已转换成使岩石产生振动的弹性能。振动区域内的介质获得弹性能后,将产生弹性振动,并以地震波的形式从爆源向外传播。因为爆破而使振动区域引起强烈振动,使在爆区周围的建筑物、构筑物往往遭到破坏。人们为寻求爆破地震效应的破坏规律,确定爆破地震效应的安全范围,采取有效防
(A) the question raised Blasting explosion blasting seismic explosions generated in the blasting of explosives in the soil rock phenomenon. That is, a small portion of the explosive energy released by explosives during detonation has been converted into elastic energy that causes the rock to vibrate. When the elastic medium in the vibration area gets elastic energy, it will produce elastic vibration and propagate outward from the explosion source in the form of seismic waves. Because of blasting, the vibration area causes strong vibration so that the buildings and structures around the explosion area are often destroyed. People seek the law of destruction of the seismic effect of blasting, determine the safety scope of the blasting seismic effect, adopt effective anti-
