摘要(Abstract):

结合茂名电厂双曲线冷却塔爆破拆除工程实例,分析总结了高大冷却塔的结构特点和失稳倾倒机理。在此基础上,采用力学原理分析了爆破切口圆心角和高度等主要参数的计算方法,对类似工程有理论和实践指导意义。
According to the blasting demolition practice of a hyperbolic cooling tower in Maoming power plant,its structural features and destabilizing mechanism were analyzed and summarized.On this basis,a method of calculating the main blasting parameters,such as the central angle and height of blasting cut,were put forward by applying mechanics principle,which has guiding significance for similar projects in theory and practice.
