Construction of Steel Tube Concrete Arch Bridge after Axes Change
In this paper ,the axes of a three-span dumbbell-shaped steel tube concrete arch bridge was changed due to deviation in bridge piers, tie beam construction and steel tube production, thereby steel tube arch ring can not be closed, and suspender hole can not be aligned. The side-span hollow steel tubes were intercepted and adjusted for three times through calculation and analysis, therefore the structure stress is reasonable and achieved original design standards under the condition of not changing the original arch axes, and the bridge was successfully constructed, thereby providing reference for engineering staff.
