| 摘 要： | 本文通过对砖砌烟囱爆破拆除的实例分析得到,在砖砌烟囱的爆破拆除倾倒过程中,其倾倒支点是不断移动的,随着烟囱主体的不断下沉,相对于未垮部分的烟囱主体来说,该支点沿烟囱筒体不断向上移动。这表明,不能简单地按刚体模型描述砖砌烟囱的倾倒运动。

| Abstract: | In this paper, an analyzed result.obtained from observations of demolished brick-chemney in toppling process, shows that the fulcrum position of the toppling chemney is moving with time. With the descending of the brick-chemney, the fulcrum position is continueously moving up relative to the un-collapsed part of the chemney.lt demonstrates that the rigid model could not be used to describe the toppling process of a demolished brick-chemney. |
