索梁锚固构造是混凝土梁斜拉桥受力分析的关键部位。当双索面斜拉桥截面悬臂较长时，需要设置悬臂式索梁锚固结构。目前索梁锚固结构主要采用把斜拉索锚固在腹板上的形式，较少采用悬臂式锚固形式。因此，在本文借助有限元的分析方法，分析了悬臂式索梁锚固结构的应力分布规律，同时提出了通过适当布置预应力钢筋来改善结构受拉状态的方法，以及降低应力集中影响的措施。

The cable - girder anchor structure is the key zone of tress analysis for concrete beam cable-stayed bridges. The cantilevered cable-girder anchorage structure is needed set-ting when the cantilever of cross section on double plane cable-stayed bridge is longer. The form that the stay - cable is an-chored on web is mainly used in The current cable-girder an-chor structure, but the form that the stay-cable is anchored on cantilevers is used less recently. The thesis analyzed the stress distribution laws in cantilevered cable -girder anchorage struc-ture by the method of finite element, and proposed some effec-tive measures improving excessive tensile stress by decorating prestressed reinforcements properly and reducing stress concen-tration.
