摘要(Abstract)：

在我国西北严寒且高地震烈度区域的某市中心地带，3栋既有建筑因存在重大安全隐患需拆除。这3栋楼房抗震等级高、结构坚固，给拆除工作带来较大挑战。为确保爆破拆除安全顺利进行，开展了严寒环境下工业电子类管组网起爆实验，充分验证了1万发工业电子雷管以及11台起爆器的起爆可靠性。基于上述实验结果、建筑物结构及周边环境特点，提出3号楼机械拆除，1、2号楼房一次性爆破拆除的总体方案。其中1号楼采用原地逐跨坍塌爆破方式，2号楼采用单向折叠倒塌爆破方式。爆破完成后，两栋楼房解体充分，拆除效果良好，达到了预期目标。工程实践表明:针对高抗震核心筒结构对楼房倒塌与解体过程的影响，通过在严寒环境下开展工业电子雷管组网起爆实验，并结合精准控制起爆延期时间与优化爆破切口等关键技术措施，可实现楼体严格按照设计预期完成倒塌与解体，从而最大限度保障周边建筑、道路及市政管网的安全。该方案为严寒环境下的高抗震核心筒结构拆除作业提供了高效安全的解决方案，并为类似拆除爆破工程施工提供了有益借鉴。
