摘要
东北汽配城为框架结构,总建筑面积46700m2,周边环境非常复杂。该建筑物共有260根柱子,断面尺寸不尽相同。按建筑伸缩缝将楼房分为5个部分,分别采用了原地坍塌、定向倾倒、折叠倾倒一次控制爆破技术,并将土石方爆破的斜线起爆技术用于拆除爆破。由于爆破设计、施工及安全措施得当,爆破获得圆满成功。
The building of Northeastern Automobile Parts Market was in frame structure, with a total building area of 46700 m^2, and was located in very complicated surrounding environment. Besides, the building had 260 supportive pillars with varying section dimensions in total. Based on the structural fea- tures, the building was divided into five sections according to its expansion joints. With the five sections demolished by employing the schemes of collapsing in situ, directional falling, folding collapse with simultaneous controlled blasting respectively, and also with the introduction of oblique initiation technique used in earth and stone blasting into demolition blasting,the demolition of the building saw a complete success.
