Abstrakt:

It is difficult to understand the mechanical performance of large-span and super-width steel box girder during the incremental launching construction, and it varies with the number of temporary piers. Combined with the engineering example of Qilu Yellow River Bridge in Jinan, this paper conducts research on the layout of temporary piers. Firstly, stress envelope of main girder and maximum support reaction forces under different layout schemes are analyzed with the frame model. Then, the local plate-shell model is used to obtain stress distribution of main plates and local stability of main girder segment under the most unfavorable loading conditions. The results show that local mechanical performance of steel box girder plays a crucial role in ensuring its safety during the incremental launching construction. Besides, rational spacing between temporary piers is 70m for Qilu Yellow River Bridge.
