The rapid development and progress of urbanization has also driven the further development of transportation and construction
industry on a certain level. If we really want to ensure the overall and effective improvement of the longitudinal pier height
difference for the corresponding seismic performance of the bridge itself, we should also continuously strengthen the detailed
grasp of the height difference in the construction process, so as to reduce the appearance of some obvious constraints. It is also
under such basic conditions that this paper carries out a more in-depth study and discussion from three perspectives: a brief
overview of height difference, precautions for bridge seismic response work, and research on the influence of longitudinal pier
height difference on bridge seismic response, which also ensures the daily travel safety of the people to a great extent
