摘要
介绍了两栋复杂环境危房的爆破拆除，分别为排架结构加框架结构的混合结构和砖混结构的五层楼。根据周围环境和待爆建筑物的结构特点，简要分析了排架结构失稳下坠时的受力状况，排架结构加框架结构的混合结构采取纵向逐排爆破倒塌的方案，较好地控制了倒塌方向和范围。
In this paper,demolition blasting situation of two dangerous buildings in complex surrounding is introduced.One is mixed tructure building with bend construction and frame construction,the other is five story building of the brick and concrete structure.On he basis of special feature of the surroundings and the blasted building ,the loading state when bend construction falling is analyzed briefly.Demolition blasting plan of mixed structure building with bend construction and frame construction is blasted one by one longitudinally,collapsing direction and rang are better controlled.
