摘要(Abstract)：

在建筑物爆破拆除方面 ,以某些实例论述了定向倒塌、定向折叠、原地坍塌、逐跨坍塌、内折倒塌等 5种常用的爆破拆除方式。在构筑物爆破拆除方面 ,讨论了基坑支撑、薄壁筒仓以及烟囱和水塔等高耸构筑物的拆除方法 ,并以实例论证了水压爆破拆除薄壁容器状构筑物的优越性。在爆破安全方面 ,强调了预防飞石、爆破降震、防尘以及准确定向的重要性。作者认为 ,只有解决好上述安全问题 ,拆除爆破在城市的建设和改造中才能发挥更大的作用
In the aspect of blasting demolition of buildings,some practical examples were taken to expound five kinds of conventional demolition modes such as directional collapsing,directional folding,in situ collapsing,piecewise collapsing and introversive collapsing In the field of blasting demolition of structures,the methods of demolishing pit shoring,thin wall silos and towered structures such as chimneys and water towers are discussed and the advantage of demolishing thin wall container like structures by water pressure blasting was demonstrated in a practical example For blasting safety,authors stressed the importance of flying rock protection,blasting vibration reduction,dust prevention and correct orientation Authors think that only by well solving the above mentioned safety problems can the demolition blasting play more important role in construction and reform of cities
