| 摘 要： | 独塔单索面斜拉桥,斜拉索对主梁抗扭不起作用。为了分析此类桥梁主梁的抗扭问题,以恩施施州大桥为研究对象,采用通用有限元程序ANSYS进行仿真分析,计算出模型在不同荷载工况作用下扭转畸变的效应。分析所得的结论对单索面独塔斜拉桥的设计和施工有一定指导意义。

| Abstract: | The stay cables of cable-stayed bridge with a single pylon and single cable plane do not provide torsional resistance for main girder of the bridge.To analyze the torsional problem of the main girder of such type of the bridge,the Shizhou Bridge in Enshi is taken as the research object and the universal finite element program ANSYS is used to conduct the simulation analysis and to calculate the torsional distorsion effect of the bridge model under different load cases.The conclusions generalized from the analysis in the paper are of certain guidance to the design and construction of cable-stayed bridge with a single pylon and single cable plane. |
