| Abstract: | When the tall and thin wall barrel structure is demolished by controlled demolition technology,the shape and size of the cut is the key of whether the barrel structure will collapse smoothly or cause recoiling and deflection and guaranting the quality and security of the explosive demolition practice.Taking an explosive demolition practice of reinforced concrete cooling tower for example,this paper introduces the parameters of cut length and height and demolition of a 60 m tall and thin wall hyperbolic curv... |
