1) box girder of approach span
引桥箱形梁
2) box girder bridge
箱形梁桥
1.
This paper is intended to study and analyze the problem of calculating the transversal internal force of the top plate in the design of a box girder bridge,and the effect of the vertical deflection of a bridge is taken into account.
针对箱形梁桥设计中桥面板横向内力计算问题进行分析，探讨了考虑桥梁纵向挠曲作用对横向内力计算的影响，以及在横向框构中考虑材料在应力─应变的线性与非线性关系两种不同状况下内力分布的变化，提出了箱形梁桥横向内力在工程设计中的计算机分析方法，编制了计算程序，并对实例进行计算比较。
3) box-girder bridg
箱形桥梁
1.
Nowadays, box-girder bridges are widely used for their large stiffness of torsion,good performance on bearing stress, suitable for all kinds of construction methods.
论文针对现行《公路钢筋混凝土及预应力混凝土桥涵设计规范》(JTG D62-2004)中斜截面抗剪承载力计算公式主要适用于矩形、T形、I形等小型开口截面桥梁，没有明确给出大型箱形截面桥梁的抗剪承载力计算公式，因而采用大型非线性有限元软件对箱形桥梁的抗剪承载力进行研究。
4) changeable height trunk bridge
变高度箱形梁桥
1.
Research of changeable height trunk bridge silent-capacity test;
变高度箱形梁桥静载试验研究
5) truss_beam bridge with box_section
箱形截面桁梁桥
6) composite box girder bridge
结合箱形桥梁
