摘要(Abstract)：
待拆建筑物与主体结构相连 ,并处在离地面 17m的高度上 ,要求爆破时周围所有功能部门均须保持正常营业。根据上述特点 ,决定混凝土顶板和侧墙采用切割机分割和吊运的方法予以拆除 ,而钢筋混凝土梁和立柱则用爆破方法拆除。本文介绍了爆破参数设计、结构的力学分析、隔振技术和防护措施等
The structure to be demolished is connected with main construction and has an elevation of 17m from the ground. It is called for that normal business of all function departments surrounding the structure must be kept when blasting. According to above mentioned features, it is determined that the concrete roof and walls are demolished by use of a cutting craning method while the reinforced concrete beams and posts are demolished by blasting method. In this paper, the design of blasting parameters, mechanical analysis of the structure, vibration isolation tech nology , safety precautions and others are introduced.
