摘　　要：介绍了一座独塔双索面曲线斜拉桥方案设计的内容,包括结构体系选择、主梁类型选择、索塔横向受力研究及斜拉索索形选择等。为确保结构安全,建立有限元模型进行了详细的静、动力分析,结果表明斜拉桥各部分构造合理可行。This paper introduces the scheme design of a curvilinear cable-stayed bridge with single-tower and double- cable planes, which includes the selection of structural system and main beam types, the lateral force research in tower and the choice of cable shape. To ensure the structural safety, a finite element model is established for static and dynamic analysis, the results show that all parts of cable-stayed bridge is reasonable and feasible.
