摘  要:矮塔斜拉桥是介于连续梁桥和普通斜拉桥之间的新型桥梁,其受力以主梁为主,拉索为辅。本文通过有限元软件MIDAS建立全桥模型,对主梁最大双悬臂状态及成桥状态进行受力分析,并获得相关结论,可为同类桥型设计提供参考依据。Low tower cable-stayed bridge is a new type of hybrid structure between continuous bridge and cable-stayed bridge based in the main girder and cable supplement of the force .Finite element software called Midas/Civil was used to build up calculation model of the bridge ,then focused on ana‐lyzing the structural behavior at the stages as follows :the maximum twin cantilever ,end of construc‐tion state .On the basis of it ,proposes the maximum internal force of construction process shall be the control basis ,and need further analysis of NO .0 block of similar bridge ,in the hope of providing ref‐erence to the similar bridge .

关 键 词:矮塔斜拉桥 主梁受力 最大双悬臂状态 成桥状态
