［摘要］在桥梁建设中，常常由于桥位处的地形限制，或者由于高等级公路对线形的要求而将桥梁做成斜交，斜桥虽然有改善线形的优点，但由于斜度的影响，受力特点与正桥也有较大的不同，其受力状态分析十分复杂。针对不同斜交角的斜交空心板梁桥进行有限元分析，运用MIDAS/Civil建立有限元模型，理论分析斜交空心板梁桥荷载横向传递规律，为桥梁的承载能力检测与评定中荷载试验的控制截面选择提供理论依据，在实际工程运用中具有参考价值。

Abstract: In bridge construction, because of the topography limiting at the bridge site, or requirements of high-grade highway for linear， bridges usually be made of skew bridge. Although there are advantages to improve the bridge of linear, but due to the affection of the tilt degree, the mechanical characteristics is also quite different between the skew and main bridges, and its stress state analysis is very complex. MIDAS/Civil software was used to establish finite element model to analyze different skew angle oblique hollow beam bridge and skew plate girder bridge lateral load transfer law in theory, which provides a theoretical basis for load testing of control surfaces selection and assessment of the carrying capacity, and has a reference value in practical engineering.

Keywords: skew hollow slab bridge; load test; finite element method; transverse load distribution
