波形钢腹板-PC组合箱梁矮塔斜拉桥参数分析

摘要

Based on waveform steel web-PC combined box girder short tower cable-stayed bridges as examples, this paper utilizes Midas to establish a model for analysis of parameters to obtain the relation between rigidity of piers and internal force of girder and that between bridge tower height-span ratio and internal force of girder and force of stayed cables, which can provide reference for design of such bridge types in the future.%以波形钢腹板-PC组合箱梁矮塔斜拉桥为例,运用Midas建模进行参数分析,得到桥墩刚度与主梁内力的关系,桥塔高跨比与主梁内力以及斜拉索索力的关系,可为今后该桥型的设计提供参考.
