中文摘要	为了研究锚拉板式索梁锚固结构在设计荷载下的应力分布及传力机理,对某斜拉桥锚拉板式索梁锚固区进行了足尺模型静力加载试验,得到各受力区域在不同荷载等级下的应力分布情况;利用ABAQUS建立索梁锚固有限元模型,按Von Mises强度理论分析其承载性能,并与试验结果对比。结果表明:在设计荷载作用下,该结构整体处于弹性工作状态,满足设计承载能力的要求;锚拉板与锚拉筒的侧焊缝根部圆弧区出现较大应力集中;上加劲板以上的锚拉板部分,最大应力出现在中部槽口中间位置;钢箱梁区域的整体应力水平较低;该结构各构件应力传递路径明确,设计时建议加大锚拉板与锚拉筒侧焊缝根部圆弧半径。; To study the stress distribution and stress transfer mechanism of the cable-to-girder anchorage structure of tensile anchor plate type under the designed load,the static loading test of the full-scale model for the cable-to-girder anchorage zone of tensile anchor plate type of a cable-stayed bridge was carried out and the stress distribution in the different loaded areas of the model subjected to the different levels of loads was obtained.The ABAQUS was also used to set up the finite element model for the anchorage zone,the bearing behavior of the model was analyzed on the basis of the Von Mises strength theory and the analysis was compared to the test.The results of the test and analysis reveal that under the designed load,the cable-to-girder anchorage structure stays in the range of elasticity and can meet the requirements of the designed bearing capacity.The great stress concentration appears in round arc area of the side welding seam root of the tensile anchor plate and anchor socket.In the part of the tensile anchor plate on the upper stiffening plate,the maximum stress appears in central position of the middle groove.The global stress level in the area of the steel box girder proper is low,the stress transfer paths of all different components of the anchorage structure are clear and it is proposed that in the design,the radius of the mentioned round arc area should be enlarged.
