摘要(Abstract)：

该楼体为框架结构,是车间楼和办公楼的结合体,由于加工面粉设备流程的需要,该楼同时承受动荷载和静荷载。楼体按照伸缩缝分为3部分,每部分的结构不相同,同部分不同层结构也各异。在爆破过程中严格控制各种参数,并采取有效的减振与防护措施,使此爆破工程在安全和质量上都达到了预期效果。
The building to be demolished was a frame structured complex of workshop and office building.Required by the flowsheet of flour milling equipment in the workshop,this building was subjected to bear both dynamic and static load.And it was divided into three sections based on its dilatation joints,with each individual section and that in different storey having different structure.Considering the building′s features,the blasting was conducted by strictly controlling the operational parameters cooperated with effective vibration reduction and protection measures,and reached anticipated effect in terms of safety and quality.
