用“倾而不倒”的演习工程探讨建筑物爆破倒塌的参数

An Exploration of the Cut Parameter of Building Blasting Collapsing in the Special Case of "Tilting without Collapsing" Drilling Engineering

因消防演练工程的需要,要求将一幢4层框架楼房爆破成“倾而不倒”以供演练,通过本工程的特殊情况,比照爆破设计与实际爆破后相关数据,探讨建筑物爆破倒塌的切口参数,对拆除爆破工程的现实参照有较好的借鉴意义。同时,还对“电子对射探头紧急自动起爆装置”作了简要的介绍。

Due to the fire-fighting drilling engineering , a four-story building of a frame structure must be blasted to make it “tilt without collapsing” for the drilling. With the special circumstances of this engineering, blasting design and relevant data after actual blasting were compared to explore the cut parameter of the blasting collapse of the building, which provides significant referential value for practical use by demolition blasting engineering. This paper also provides a brief description of the “electronic correlating probe emergency automatic detonation device”.
