【摘要】 在控制爆破拆除高耸筒体建筑物时 ,建筑物的倾倒过程是一个复杂的力学过程。本文利用两种模型对倾倒过程进行了力学分析 ,并在中上部可能出现折断的问题上得到了与前人不同的结论。本文在分析中同时给出了一些必须参数的精确的数学表达式。更多还原

【Abstract】 The fall down process of high tubular type buildings(chimney,tower etc)demolished by means of blasting is a complicated process of mechanics.Two kinds of mathematic models to analyse the mechanics in the fall down process are introduced by which some conclusions other than usual are obtained about the break possibility of buildings at their upper or middle parts when they fall down.Besides,precise mathematic expressions of some necessary parameters are given.更多还原
