摘　　要：文中针对多跨斜交现浇箱梁,分析了其支座布置方式。由于多跨斜交现浇箱梁支座受力复杂且影响因素较多,布置前期需进行有限元建模分析,评估不同布置方式下支座的受力状态及整桥结构性能,以降低工程造价及后期返工率。This paper studies the multi-span skew cast-in-place box girder and analyzes the support arrangement.Due to the complex forces and many influencing factors on the support of multi-span skew cast-in-place box girder,finite element modeling analysis should be carried out in the early stage of layout to evaluate the stress state of the support and the structural performance of the whole bridge under different layout methods,so as to reduce the project cost and rework rate in the later stage.
