摘　　要：自锚式悬索桥主缆锚固区承受强大的索力且构造复杂,是该桥型设计和研究的重点.以实际工程为例,应用有限元方法对其混凝土锚固区进行空间应力分析,探讨了锚固区在强大索力作用下的受力特点及索力传递规律,并采用光弹试验验证有限元计算结果的准确性.分析结果表明,该模型计算结果准确,结构传力合理、可靠.The cable anchorage zone of self - anchored suspension bridge is one of the keys in design and study of this type of bridge because of its great cable forces and complex structure. In this paper, the rule of stress distribution and transmission of the RC zone subjected to huge cable forces is ana- lyzed in detail by modem finite element method （FEM） based on a practical engineering, and the reli- ability of the results is tested by photo - elastic experiment. It is found that the results of FEM is de- pendable, and the transmission of the loads in the zone is reasonable and sufficiently safe.
