摘　　要：介绍郭家沱长江大桥索夹的整体设计及减小或消除短吊索2次应力的措施。实体有限元受力分析表明,该桥索夹设计应力水平适当,结构设计合理,可为后续的优化设计提供依据。This paper introduces the overall design of the cable clamps of Guojiatuo Yangtze River Bridge and the measures to reduce or eliminate the secondary stress of the short suspenders. The stress analysis of the solid finite element shows that the designed stress level of the cable clamp is suitable and the structure design is rational,which provides basis for future optimization design.
