与常见的柱式桥墩相比,双肢板式桥墩的盖梁在内力分布上有着显著的不同。该文以乌干达Kampala-Entebbe高速公路中的车行天桥为例,分别采用了平面刚架和三维实体两种模型进行计算,通过对比分析,探讨了该类桥墩盖梁的受力特点。 Compared with the common column piers, the beam with double-limb plate piers has a significant difference in the distribution of internal forces. Taking the railway bridge in the Kampala-Entebbe expressway in Uganda as an example, two models of plane rigid frame and three-dimensional solid were used respectively to calculate. By comparing and analyzing, the force characteristics of the bridge girder of such pier was discussed.
