520			_aThis paper studies the influence of departure slope on the vertical attitude deviation of long-distance jacking for super-large frame box culverts. Closely combined with the engineering example of the overpass project for Tongling North Road under Hefei East Railway Station, the whole process evolution of the long-distance jacking attitude for the box culvert under different starting slopes and multiple working conditions is studied by using the numerical calculation method firstly. The numerical results show that in the process of long-distance jacking of super-large box culverts, the maximum lifting amount of box culverts on the whole increases with the increase in the initial slope, and it is beneficial to control the vertical attitude deviation of box culverts when the initial slope is flat. Finally, the rationality of the conclusion is verified by inverse analysis of monitoring data for the box culvert jacking project. The research results provide the theoretical basis for correctly understanding and reasonably judging the attitude control of long-distance jacking of super-large box culverts. At the same time, it is provided case support and the reference basis for similar engineering construction.
