摘要
从理论上研究了冷却塔在倾倒过程中，转角θ与时间ｔ之间的关系。对于支撑部分保存完整的冷却塔，计算结果与实测结果基本吻合，相对误差小于１０％。实际倒塌长度与理论倒塌长度之比为０．９８，实际倒塌中心线与理论倒塌中心线左右偏差３．１８°，倒塌初始时刻冷却塔未下坐，当ｔ＞０．６ｓ之后，冷却塔开始下坐，下坐高度与倾倒时间成正比。最后，还分析了冷却塔在倾倒过程中的前冲和后坐问题。
The falling processes of cooling towers in destruction work are introduced In thispaper.The relation between the turning angle of the cooling tower and the falling time is calculat-ed theoretically.The calculated results are in good accord with that of the practical,the relativeerror is less than 10%. For example, the relative error of the falling length is 2%,the practicalfalling center line devilates form the theoretical about 3.18°. The cooling tower did not sinkdownward. Until after 0. 6s of falling taken place. Lastly,the problems of push forward andsinking downward are discussed as well.
