摘要
通过对钢筋混凝土烟囱爆破拆除过程中余留截面破坏的各阶段进行力学分析,建立了钢筋混凝土烟囱定向倾倒的条件及切口角度和高度的数学模型。通过工程实例分析,验证了所建数学模型的准确性。
According to the mechanical analysis of different falling stage on the remainder cross section during the blasting demolishing of a steel concrete chimney.the condition of directional falling of a steel concrete chimney and its mathematic model is presented. The mathematic model＇ s veracity is verified after analyzing an engineering example.
