摘　　要：以海南横线高速公路定安河段桥梁工程为依托,该桥梁所处地段受整体规模、现场金矿及水电站、水文条件等多方面因素影响,导致路线走廊带选取受限,桥梁需沿河布设,且两次跨越河道。桥梁在总体方案、墩台布置、水文计算、结构设计等方面均与常规桥梁存在差异。总结并归纳出相关设计重难点,对曲线连续刚构桥的详细构造和整体受力特点进行分析,为同类桥梁设计提供参考。The bridge construction locates in Ding’an River section of the Hainan Hengxian Expressway where diversified restrictive factors,such as overall scale,on-site gold mines,hydropower stations and hydrology condition,contribute to the difficulty in design stage and construction process.On this condition,the bridge is modified to align along the riverbank and cross the river twice,resulting in the noticeable differences from conventional bridges in terms of overall scheme,pier layout,hydrological calculation and structural calculation.Summarized the key and difficult points of relevant design.Detailed structural design of curved continuous rigid frame bridge and overall bridge stress characteristics would be thoroughly discussed,providing a reference for the design of similar bridges.
