矮塔斜拉桥结构特征参数研究

以一座已建成的矮塔斜拉桥——山西太原汾河大桥为研究对象,利用Midas建立有限元分析计算模型,通过调整不同的结构参数,对矮塔斜拉桥的结构内力及变形的影响因素进行了分析,进而得出了该类桥型在不同支承条件、塔高及边主跨比的条件下,矮塔斜拉桥的索力、主梁内力及变形的变化情况。

Structural Characteristic Parameters of Low-Pylon Cable-Stayed Bridge

Taking a low-pylon cable-stayed bridge--Taiyuan Fenhe Bridge in object, a finite element model is established using Midas software. By adjusting the Shanxi Province as research parameters of structure, the influencing factors of structural internal force and deformation of low-pylon cable-stayed bridge are analyzed. Furthermore, the situation about the change of cable force, internal force of girder and deformation of low-pylon cable-stayed bridge under different supporting condition, pylon height and side-to-main span ratio is obtained.
