目前， 在新建房屋及旧房改造中， 有关悬挑结构倾覆、坍塌的事故时有发生， 从悬挑结构坍塌实例来看， 表现为三种形式： 整体倾覆坍塌、沿悬臂梁根部的断塌及悬挑构件下砌体局部受压破坏． 本文从设计、施工及使用角度系统地分析了悬挑结构坍塌事故发生的原因， 如采用不正确的计算方法、模板支撑方案不当、施工超载、拆模过早、不正确地使用等， 并对这些原因提出了切实可行的防治措施和处理方法．
At present, in the reconstruction of newly-built houses and old houses, accidents involving overturning and collapsing of cantilever structures occur from time to time. From the example of collapsing cantilever structures, there are three forms: Overall overturning collapse, collapse along the cantilever beam roots And cantilever members under local pressure destruction. This paper systematically analyzes the causes of collapse accidents of cantilevered structures from the perspectives of design, construction and use, such as using incorrect calculation methods, improperly supporting the template, overloading the structures, prematurely removing the molds, and using them incorrectly. These reasons put forward practical measures for prevention and treatment.
