摘　　要：盖梁抱箍法施工是一种无支架盖梁施工工艺,是通过抱箍与墩柱之间的摩擦力承担盖梁施工荷载,不受地形影响,节省支架,施工简便,降低施工成本,便于现场文明施工,且能缩短工期,加快施工进度,提高经济效益。主要通过漳河大桥引桥盖梁为例,阐述抱箍法盖梁施工工艺、施工方法、质量验收标准及验收指标等,验算盖梁施工中的抱箍应力是否满足施工要求。The method of using cap beam holt hoops for construction is a non support cap beam construction technique.It bears the construction load of the cover beam through the friction between the hoop and the pier column,which is not affected by terrain,saves support,and is easy to construct.It also reduces construction costs,facilitates civilized construction on site,shortens the construction period,accelerates construction progress,and improves economic benefits.Taking the approach span cover beam of Zhanghe Bridge as an example,this paper elaborates on the construction technology,construction method,quality acceptance standards,and acceptance indicators of the hoop method cover beam,and verifies whether the hoop stress during the cover beam construction meets the construction requirements.
