摘　　要：在悬臂桥建设中,0#托架施工常采用焊接托架及销接托架施工工艺,为了对比这2种工艺的适用性,结合实际工程从设计、施工、材料、成本、质量控制等方面进行了分析,结果表明2种类型的托架均具有其优异及缺点,销接托架相对于焊接托架更加省人工及时间,减少高空焊接工作,降低了安全事故发生的概率,能提高施工安全性。the construction of cantilever bridge,welding bracket and pin joint bracket construction technology are often used in 0#bracket construction.In order to compare the applicability of the two technologies,the design,construction,material,cost,quality control and other aspects are analyzed combined with the actual project.The results show that the two types of brackets have their advantages and disadvantages,and the pin connected bracket is more labor-saving and time-saving than the welding bracket It can reduce the high-altitude welding work,reduce the probability of safety accidents,and improve the construction safety.
