摘要:
介绍了城市复杂环境中采用双切口对向倒塌爆破拆除两栋高层框架核心筒结构大楼的工程实例。根据框架核心筒结构特点，结合场地周边环境，选择对向倒塌的爆破方案。先爆建筑采用双切口方式，后爆建筑采用单切口方式，通过四通与簇联相结合的复式起爆网路，楼间间隔3 s延时起爆，实现大楼逐栋倒塌解体；采用主动防护与被动防护相结合的安全防护技术，有效地控制了爆破振动、塌落振动和爆破飞散物，取得了良好的爆破效果。
Abstract:
An engineering example of demolishing two high-rise buildings with frame-core tube structure by double incision and opposite direction collapse blasting in a complex urban environment was introduced. According to the structural characteristics of the frame core tube and the surrounding environment of the site, the opposite collapse blasting scheme was selected. Double-incision blasting method was adopted for the first blasted building, and the single-incision blasting method was adopted for the later blasted building. Multiple initiation network combined with four-way and cluster connection was used. The delay time of initiation between the buildings was three seconds, and the buildings collapsed and disintegrated one by one. The safety protection technology combining active protection and passive protection was adopted to control blasting vibration, collapse vibration and flying objects effectively, and good blasting outcomes have been achieved.
