大型钢结构厂房拆除控制爆破总体方案设计

GENERAL PLAN FOR DEMOLITION OF LARGE-SCALE STEEL-STRUCTURAL FACTORY HOUSE BY CONTROLLED BLASTING

系统地阐述了钢结构物爆破拆除面临的主要问题,这些问题包括爆破方案设计的思路、线性聚能切割器的作用原理与定型、利用结构稳定性原理设计结构爆破预处理的参数以及切割爆破的主要危害等。以上钢一厂钢结构厂房的切割爆破拆除为例,讨论了爆破总体方案设计、不同连跨结构的倾倒方式、切割器的设置以及安全防护的措施等。

The key problems met in blasting demolition of steel structures are systematically expounded These problems include the concept of blasting plan design,the work principle and determination of linear cumulative charge,the design of blasting parameters for structure pretreatment by the principle of structural stability,main harms of cutting blasting and othersTaken blasting demolition of steelstructural factory houses in First Factory of Shanghai Iron & Steel Company as an example,design of general blasting plan,collapsing modes of different combined steel structures,fixation of cutting charge and safety precautions are discussed
