摘要(Abstract)：

结合具体工程实例介绍了大直径双曲线薄壁钢筋混凝土冷却塔定向爆破拆除的技术特点。合理地选择了爆破切口等主要爆破参数,对爆破飞石、爆破振动、碎碴飞溅等进行了安全性分析并提出具体的安全措施,工程实践表明爆破效果良好,已达到安全拆除的目的,同时对同类工程的设计和施工具有参考价值。
According to a specific project,the technical features that a cooling tower with large diameter was demolished by the directional blasting were introduced.The cooling tower was made of reinforced concrete and thin-walled hyperbolic structure.Main blasting parameters such as blasting cut were chosen reasonably.Safe analyses on flying stones generated by blasting,blasting vibration,crushed slag splashing etc were carried out,and specific security measures were proposed.The engineering practice shows the blasting effect was good and the aim of safe demolition was achieved.It has reference value for design and construction of similar project.
