Abstract：
In this paper, construction control was researched taken the Liulintan Yellow River Bridge for engineering background, which is a continuous rigid-frame bridge with multi-span and long span for heavy-load highway. Adaptive control system was used combined with structural characteristics of the bridge. Kalman filtering method was used for measurement error and identification error of physical parameter. The method of earth absolute coordinate system was used to control bridge's axis. The method of absolute elevation was used to control deformation of vertical deflection. The whole process concrete stress monitoring in the most unfavorable section of girder was implemented by using concrete strain meter with intelligent temperature compensation function. Through analysis of final closure error, final bridge alignment and most unfavorable stress, that is indicating full-bridge alignment control is good, stress monitoring is correct and structure is safe in whole construction.
