| 摘 要： | 钢桁梁-混凝土板组合梁桥是混凝土桥面板与钢桁架结合共同受力的一种新型组合结构。现对80m双线下承式钢桁结合梁-混凝土桥面板两种结合形式的有限元计算结果对比分析，研究桥面系和下弦杆的受力差异，通过对比分析得知，全结合桥面系结构较为合理。

| Abstract: | Steel truss-concrete girder bridge which is a common bearing structure formed by the concrete slab and steel truss is a new kind of combined structure.Through the comparative analysis of finite element results of the two combined forms of 80m for through type steel truss-concrete girder bridge with two-lane railways,we study the force difference about the bridge deck system and bottom chord.Finally,we get that the structure of full bonding bridge deck system is more reasonable. |
