摘　　要：控制爆破拆除复杂环境下85m高钢筋混凝土冷却塔,是国内迄今为止爆破拆除最高的冷却塔。爆破采用预开天窗和减荷槽的复式爆破缺口,选择合理的爆破参数,并采用封闭式防护和开挖减振沟及铺设缓冲垫层等安全防护措施,爆破达到了定向准确、安全、破碎好的效果,为类似爆破工程提供参考。This paper presented a blasting demolition of an 85m high cooling tower in reinforced concrete and located in complicated environment,which was up to now the highest one in China.The blasting employed composite trapezoidal gap with pre-cut skylights and load reducing groove,chose reasonable parameters and reasonable security measures,which responsible for achieving better blasting results,and hence,resulted in accurate direction,safety operation and proper crush in fragmentation size.The paper provided reference for the similar project.
