Research on Influences of Construction Parameters of PC Continuous Steel Structure Bridges on Disintegration of Baseplates

TIAN Shiqing,LI Maosheng,SHI Qingfan  
In accordance with disease features of disintegration of baseplates close to the middle of main span of PC continuous steel structure bridges,this paper calculates local stress of baseplates at closure sections by means of finite element analysis software,comparatively analyzes influences of relevant changes of construction parameters such as thickness of baseplates,diameter of corrugated pipes,protective layer of corrugated pipes and space between corrugated pipes,etc.on local stress of baseplates,and proposes a series of suggestions for construction design preventing disintegration of baseplates.
