摘要
介绍了复杂环境下一特殊结构厂房进行分区爆破拆除的方案设计。为保护主控室在爆破时不受损害,能安全正常工作,采用对大板梁支撑立柱在不同高度处布置爆破区并进行逐次延期起爆及一些传统的减振方法,使主控室处的质点振动速度小于0.25 cm/s,确保了厂房的爆破成功。
The blasting demolition of a large workshop with special structure by span collapse under a slashing condition is introduced. To protect the master chamber and keep it working normally, dynamiting at different altitude on poles which support the large boards and traditional methods which reduce vibration are adopted. Such technical measures ensure that the vibration speed is less than 0.25cm/s at the master chamber,guarantec successful blasting of the workshop and can be used as a reference in similar projects.
