- 从动力学的观点出发,分析塔吊、吊篮等施工机具钢丝绳断绳事故原因,对塔吊等机械紧急刹车造成的危害进行了理论分析与探讨,发现这些动荷载具有很大的破坏力,提出动力计算公式和动力系数概念,并用实例加以说明。
From the view point of dynamics, the causes of wire rope breaking accidents occurred in some construction machines such as tower crane and hoisting basket are analyzed. Especially, the damage caused by emergency brake operation and the destructive power produced by such dynamic loads are theoretically discussed. The dynamic calculation formulas and dynamic coefficient concept are presented and explained by practical examples.2008,6(6): 59-61 收稿日期：2008-3-30分类号：TG142.15作者简介：蒋晓燕（1970-），女，浙江东阳人，高级讲师，注册一级建造师，同济大学工民建专业毕业，从事建筑工程教学及建筑施工与管理工作。参考文献：
