摘要
施工爆破产生的地震效应往往影响周围建筑物的安全,为了找出控制爆破地震产生的有害效应的有效措施,本文分析了爆破振动地震效应原理,指出了爆破振动速度是导致建构筑物结构破坏的一个重要物理量,它可使建筑物的正常工作受到影响。同时研究了怎样合理确定爆破地震质点振动速度,使预报更为准确。论述了控制爆破振动强度、减小振动效应的措施。
In this paper the principle of blasting vibration earthquake effect is analysed and it is pointed out that the explosion vibration velocity is an important quantity that leads to structure damage. The paper has also studied that how to confirm vibration velocity of particple which can predict blasting earthquake effect. And the measures that can contron ex plosion vibration strength and reduce viration have been disussed.
