摘要
预应力高架桥梁是城市轨道交通中常用的桥型之一,根据深圳地铁龙岗线连续刚构预应力梁体施工过程控制,分析裂缝产生的原因、对裂缝进行监测分析,并针对裂缝制定有效加固措施。
Prestressed viaducts are commonly used for city rail transit bridges.According to the construction process control for Shenzhen metro Longgang line prestressed continuous rigid frames,the paper analysed the causes of the cracks,monitored the cracks and adopted effective reinfo-rcement measures for the cracks.
