| 摘 要： | 由于路桥过渡段在结构上为塑性变形和刚度突变体,因此会由于材料不同而引起线路纵向变形,以及因工后沉降差而引起轨面弯折。通过研究分析其原因,并在施工中加以改进,以期提高高速铁路路桥过渡段在施工中的刚柔结合度。

| Abstract: | Because bridge approach is a mutant of plastic deformation and rigidity in structure,different materials can cause vertical deformation,while the post-construction settlement difference can cause the track surface bending.The reasons for these were researched and analyzed,and some improvements were introduced to increase the combination degree of flexibility and rigidity for the bridge approach in the high-speed railway construction. |

| Keywords: | high-speed railway bridge approach settlement difference vertical deformation |
