中文摘要	国内外常采用理论分析和模型试验相结合的方式来研究斜拉桥索梁锚固结构的应力特征。以某斜拉桥锚拉板式索梁锚固结构为例,采用桥梁专业计算软件MIDAS CIVIL建立全桥空间杆系模型,确定了索梁锚固区试验模型的选取位置,采用大型通用有限元软件ABAQUS建立选取节段空间板单元模型,经过对比分析,对锚拉板式索梁锚固区试验模型进行了长度、宽度和高度的优化。最终确定的索梁锚固区试验模型不仅满足了实验室场地要求、设备要求和材料的合理利用,还保持了与原桥的高度相似性,保证了后续试验的可行性。; To study the stress characteristic of the cable-beam anchorage zone of a cable-stayed bridge,the method to combine theoretical analysis and model test is usually used at home and abroad. Taking a cable-beam anchorage zone with tensile anchor plate structure of a cable-stayed bridge for example,the location of test model on the cable-beam anchorage zone was selected by space finite element model of the full-bridge that was built by MIDAS CIVIL. The space plate element model of selected segment was built by ABAQUS. Through comparative analysis,the length,width and height of test model on the cable-beam anchorage zone were optimized. Finally,test model on anchorage zones not only meets the requirements of laboratory space,equipment and the rational use of materials,but also maintain a high degree of similarity with the original bridge,and ensure the feasibility of subsequent test.
