本文将三箱并联变高度的悬臂桥,模拟成平面的弹簧支承结构来分析荷载的横向分布。可用纽玛克数值法十分简便地进行手算,并且易为设计人员掌握。文中表列的分析数据,可供初步设计参考。在技术设计阶段,可以根据具体结构尺寸进行计算。因此,本文的力学模型的优点,在于为结构配置纵横方向钢筋时,可以不用电子计算机,也能得出较精确的内力值。
In this paper, the cantilever bridges with three heights connected in parallel are simulated to form a plane spring support structure to analyze the transverse load distribution. Newman’s numerical method can be easily used for hand calculations, and it is easy for designers to grasp. The analytical data listed in the text can be used for preliminary design reference. At the technical design stage, calculations can be made based on the specific structural dimensions. Therefore, the advantage of the mechanical model in this paper is that when the structure is configured with vertical and horizontal rebars, it is possible to obtain a more accurate internal force without using a computer.
