摘要
从边中跨比、索塔高跨比、无索区长度、主梁梁高4个参数方面研究其对跨中长距离等截面矮塔斜拉桥的主梁变形、内力及斜拉索索力等结构性能的影响,分析出各个参数在此类桥型中的合理取值范围,为以后的矮塔斜拉桥设计提供参考。
This paper study on long-distance and other cross-sectional Extradossed Bridge girder deformation, internal forces and stay cable the force of impact of structural performance from the edge of the cross-ratio, high-span ratio tower, length of no cable area, beam girder high four parameters of low tower cable-stayed bridge, and analysis of various parameters in the reasonable range of such bridge, provide a reference for future low tower cable-stayed bridge design.
