| 摘 要： | 以苏通大桥为背景，调研各国规范对斜拉桥温度作用的相关规定，进而研究超大跨径钢斜拉桥的温度静力响应。研究将斜拉桥的温度作用分为体系温差、索梁（塔）温差、主梁温度梯度、主塔温度梯度四个方面分别讨论，利用考虑几何非线性影响的有限元软件ANSYS计算分析斜拉桥的温度效应及各构件对温度的敏感性。分析结果可以为今后同类桥梁的设计或计算提供参考和依据。

| Abstract: | Based on the background of Sutong Bridge, this paper investigates several codes of the temperature acts on cable-stayed bridges, and studies the static response to temperature acts of long span steel cablestayed bridges. The temperature loads consist of four parts as follows ： uniform temperature component, tempera- ture differences between cables and deck （or tower） , temperature differences for bridge decks, and temperature differences for bridge towers. ANSYS, the finite-element software considering the geometric non-linear effect, is applied to analyze the temperature effects on cable-stayed bridges and the sensitivity of each structural member. The results can be referenced for the design or calculation of similar bridges. |
