| 摘 要： | 在繁华闹市区成功地进行了一次定向爆破拆除两幢高27m的六层框架楼房。通过采取的严格措施控制了楼房的塌落振动和爆破飞石,使之既不能产生过大的后坐,又不能在倒塌后产生较大的侧向滑移。本文所介绍的爆破技术参数设计及安全防护措施,可为类似工程的实践提供参考。

| Abstract: | The top of the subject is reinforced concrete silos and the bottom is built to be frame-braced storages.Owing to its too heavy self-weight,critical vertical collapse and recoil usually occurs in directional blasting.The author introduces methods of second formation of blasting notch on the central pillars and installation of anti-recoil bracket on the rear pillars to avoid vertical collapse and strength of push-back.The work done in this paper is of reference value to the similar engineering. |
