【摘要】 介绍复杂条件下,通过采用高爆破切口、适合的爆破区域划分和区域间的爆破时间差等爆破技术参数,使建筑物能够安全的倒塌在预定的范围内;通过采用远体防护、减振沟和松散垫层等措施,有效的控制了爆破飞石、爆破振动和建筑物触地振动的危害;同时,通过此次成功的爆破经验,为非线形排柱支撑建筑结构的爆破提供了参考。更多还原

【Abstract】 The technique parameters of high blast cut,reasonable blast area division and its delay time of each other were made sure of safely collapsed within prediction zone under complex surronding condition.The flyrocks,blasting vibration and touchdown vibration were effeciently controlled by body protection,damping ditch and loosing buffer layer.Then this success of blasting provides conference for demolishing of non-linear row of columns buildings.更多还原
