摘　　要：在考虑剪力滞效应对箱梁变形影响的基础上,建立薄壁箱形梁的变形微分方程,并给出均布荷载、集中荷载作用下的变形初数解及跨中最大变形的计算公式。The deflection differential equations of thin-walled box-girders are established based on considering the influence of shear lag on the deflection of box-girder, and the deflection present analysises under uniformly distributed load and concentrated load and the most deflection calculation formulas in span are give. Numerical results that the method proposed in the paper gives utility and accurate solutions with the design and construction control of box-girder bridge. It can be very widely used in civil engineering.
