摘　　要：介绍了苏通大桥在设计过程中专门对斜拉索进行的测力试验情况,并与国外相关研究成果进行了对比,提出了斜拉索纵桥向风荷载阻力系数计算公式。该研究填补了我国桥梁抗风设计规范的空白,已被纳入《公路桥梁抗风设计规范》(JTG/T D60-01-2004),具有很高的实际指导意义。The cable force experiment was carried out during the design of Sutong Bridge. By comparing with the international research results, the calculation formula of longitudinal wind drag coefficient for cables was advanced to fill the blank of bridge wind resistant code of China, and this formula has already been adopted in the Highway Bridge Wind Resistant Design Code （JTG/T 1360-01-2004） with great significance for bridge engineering.
