悬挑结构坍塌原因分析及防止措施

Analysis on collapse causes of cantilevered structure and prevention measures

从抗倾覆能力不足、模板支撑方案不当、主筋放置不当、施工超载、拆模过早五个方面阐述了引起悬挑结构坍塌的原因,并提出了防止措施,以尽量避免悬挑构件事故的发生。

From five aspects： less antidumping factors, unfitting formwork supports, setting of main steel bar , construction overloads and form removal too early reasons caused the collapse of cantilevered structure are analyzed; at the same time corresponding prevention measures are proposed in order to avoid structural accidents of cantilevered structure.
