摘要
采用多塔悬索桥挠度理论,对三塔悬索桥的矢跨比、主塔刚度、加劲梁高度和主塔高差等进行了参数分析。通过这些分析,有利于帮助人们把握三塔悬索桥的受力特点,得出的结论可供类似桥梁方案设计时参考。
Using the deflection theory of suspension bridges with multi-tower, parameter analysis has been performed on rise-span ratio, stiffness of main tower, depth of stiffening girder and high difference between towers. Those analysis works are useful for the understanding of structural characteristics of 3-tower suspension bridges, and the conclusions drawn can be referred in scheme design stage of similar bridges.
