Construction safety accidents occurred frequently in our country every year, which resulted in high casualties and huge national poverty loss. Moreover, the harmfulness of collapse is so great that effective prevention and control for collapse accidents contributes greatly for preventing construction safety accidents. The graph intuitively introduced the change of the fatalities or injuries of our building collapse accidents from the year 2003 to 2009.Based on the analysis of data about different types of collapse accidents happened nearly in 2009, which was the fruit of related analysis method, and by exploring the percentage of different types of the accidents and their causes,some countermeasures were proposed to prevent the collapsing to achieve effective prevention in the accident.%我国建筑安全事故频频发生,伤亡人数仍居高不下,给国家经济和人民生命财产造成了重大损失.坍塌事故的危害性很高,有效防治坍塌事故对预防建筑施工安全事故有着十分重要的意义.运用图形直观地介绍了2003-2009年我国建筑业坍塌事故伤亡情况的变化,运用相关分析的方法,通过对2009年来所发牛的坍塌事故类型的数据分析,探讨了不同类型坍塌所占比例,坍塌事故发生的原因,并有针对性地提出防止坍塌的对策,以期达到有效预防坍塌事故的目的.
