摘要(Abstract):

介绍了横向切割与定向爆破综合技术在威海市香威大酒店危楼爆破拆除工程中的应用。通过合理布置横向切割缝,达到了采用较小的爆破切口成功爆破拆除小高宽比楼房的目的。灵活设置飞石防护措施和振动控制措施,确保了周围建筑设施的安全。爆破取得了良好的效果,可为类似工程提供借鉴。
The application of lateral incision and directional blasting integrated technologies in blasting demolition of the dangerous building named Xiangwei Hotel in Weihai was discussed.Under the premise of correctly arranged lateral incision slits,the demolition blasting of the building with small height-width ratio was successful using a smaller blasting cut.The protective measures for fly-rocks and the control measures for vibration were set up flexibly to ensure the safety of surrounding buildings and facilities.The blasting achieved good results.It could provide a reference for similar projects.
