| 摘 要： | 以理论推导和计算结果为基础,建立不同有限元模型,分析在不同支撑刚度下梁截面的内力变化情况,研究得出了临时支撑在不同刚度时,对简支梁内力的影响规律。研究结果表明:支撑刚度与主梁刚度比处于某一比值关系时,主梁全截面受力更均匀合理,不会出现支点负弯矩情况。并结合实桥,通过不同荷载试验,检验了研究结果的合理性。

| Abstract: | Based on the theoretical derivation and calculation results, this paper established the different finite element model to analyze the internal force changes of beam section under the different support stiffness. It obtained the influence law that the temporary support on the internal force of a simply supported beam under the different stiffness. |
