摘　　要：结合某水库区域内某处特大型桥梁设计经验,以该特大型桥梁所在库区内水位大落差变化的特点为前提,选择该桥桥型方案。通过对比悬索桥、斜拉桥和连续刚构桥的特点,分析桥梁跨径影响因素,结合地形、地貌、地质和运输条件等因素,确定桥型方案及主梁结构。In combination with the design experience of a super large bridge in a reservoir area,taking the change characteristics of large water level drop in the reservoir area of the super large bridge as the premise,the scheme for the bridge type of the bridge is selected.The influencing factors of the bridge span are analyzed by comparing the characteristics of suspension bridge,cable-stayed bridge,and continuous rigid frame bridge.In combination with the factors such as terrain,topography,geology,and transportation conditions and so on,the scheme for the bridge type and the structure of main beam are determined.
