| 摘 要： | 独塔混凝土斜拉桥的静力特性主要包括主梁受力及变形、支座反力、主塔受力及变形、拉索受力。通过改变主梁恒载重量、拉索倾角、无索区长度等结构参数,分析结构参数变化对结构受力的影响。分析结果表明,恒载重量增加会使拉索索力呈现线性增加趋势,斜拉索倾角增大对结构的受力有利,但需要考虑主塔高度增大带来的施工难度;无索区长度的增大对结构受力不利。在设计中需要考虑受力和施工的综合影响。

| Abstract: | The static characteristics of the single pylon cable-stayed include the internal force and deformation of main girder,reaction force,force and deformation of the main tower.Structural internal force is calculated by changing constant load of the main girder,the cable angle,the length of unsupported deck.The results shows that the cable tension will increase linearly with the constant load of the main girder,and the increase of cable angle will be benefit.However the construction of tower will be difficult w... |
