国内外学者对简支梁和连续梁桥上无缝线路的梁轨相互作用进行了大量的研究，而对城市轨道交通斜拉桥桥上无缝线路的梁轨相互作用的研究非常少。文中以上海轨道交通16号线上某斜拉桥（80 m＋160 m＋80 m）为背景，研究了4种不同钢轨伸缩调节器设置方案对钢轨纵向附加力的影响。研究表明，在斜拉桥两端设置钢轨伸缩力能有效地降低钢轨纵向附加力。在斜拉桥跨中设置伸缩调节器时，因斜拉桥跨度大，不能有效地降低钢轨纵向附加力，工程实际中建议在斜拉桥梁两端设置钢轨调节器。

Up to now,the existing researches on girder-rail interaction have been mainly focused on simply-supported bridge and continuous bridge,while relative works on special form bridges are still rarely.Based on a cable-stayed bridge (80 m+140 m+80 m)on Metro line16 in Shanghai,the influ-ences of different 4 rail expansion regulator setting programs on additional longitudinal forces are ana-lyzed.The result of this research shows that longitudinal additional forces reduce significantly when rail expansion is set on both of the cable-stayed bridge,while longitudinal additional forces almost do not change when rail expansion is set in the middle of the cable-stayed bridge.So,the program that rail expansion is set on both of the cable-stayed bridge is suggested in practical engineering.
