摘要:
通过对高层建筑物倒塌过程中的后坐和前冲运动的分析论述，阐明了毫秒微差爆破持续时间对运动过程的影响；介绍了毫秒微差爆破技术在18层框架结构楼房拆除中的应用情况。为减少建筑物在拆除爆破中对周边环境的影响，设计合理的爆破网路参数，并且对主楼、墙体、剪力墙等结构进行预处理；采用适当的分段延时方法使得振动叠加，控制建筑物倒塌范围，从而减少高层楼房塌落产生的危害。合理的分段时间增加了建筑结构体内力作用时间，保证了楼房的充分解体，达到了预期的爆破拆除效果。
Abstract:
By analysis and discussion of the motion of the collapse process of high-rise building, the influence of blasting duration in millisecond delay blasting on the movement process was clarified. Application of millisecond delay blasting in an 18-story frame structure building was introduced. To reduce the environmental impact of the building in explosive demolition, suitable parameters for blasting network were designed. The main building, the walls and shear walls were pre-treated. An appropriate piece-wise delay method was used to make the vibration superimposed and control the collapsing range of the building, and thus to minimize the harm of blast. Reasonable time interval increased the action time of internal force of the building and ensured the full collapse of building, so as to achieve the desired blasting outcome.
