摘要(Abstract)：

介绍了济南一座11层框剪结构大厦的爆破拆除。该大楼高宽比小、稳定性高,首先通过人工预处理被分为两个独立的建筑,然后采用控制爆破使它们分别向不同的方向倒塌。文中讨论了爆破拆除方案的比较和选择,较详细地论述了承重立柱破坏高度的设计计算、爆破参数的确定、装药结构和起爆网路。同时,用照片说明了对不同断面形状的立柱进行试爆的效果。此外,还对预处理和安全措施作了简要的介绍。
Demolition of an 11storeyed building with frameshear wall structure by controlled blasting is introducedThis building has small heighttospan ratio and high stabilityFirstly,the building is divided into two separate constructions through manual pretreatment,then making two constructions collapsing to different directions respectivelyIn this paper,the comparison and selection of blasting schemes are discussed,and the calculation of blasting cut height,the determination of blasting parameters,charging structure and priming network are expounded in detailAt the same time,the results of trial blasts for bearing posts with various section shapes are illustrated using a few photosBesides,The pretreatment and safety precautions are briefly presented
