摘要(Abstract)：

待拆除的大楼结构复杂,与旁边需保护的建筑物相距仅5.2m,必须严格控制楼房倒塌的方向、倒塌过程中的后坐和倒塌后的爆堆。为此,通过人工预处理将大楼分成两个部分,并分次进行不同倒塌方向的定向爆破拆除。文中对避免高楼爆破过程中产生后坐的技术措施和在复杂环境中楼房爆破拆除的安全措施进行了探讨。
The building to be demolished standing 5.2m apart from protective constructions had a complicated structure. And for this reason, the collapsing direction, backlash and collapsing muck-pile must be strictly controlled in its blasting demolition. For reaching this goal, the building was split into two parts by manual pretreatment, with the two parts being made collapse in different directions respectively. The technological measures which avoided backlash during the collapsing and safety measures taken in the demolition in complex surroundings were discussed in this paper.
