［摘要］在橋梁建設(shè)中，常常由于橋位處的地形限制，或者由于高等級(jí)公路對(duì)線形的要求而將橋梁做成斜交，斜橋雖然有改善線形的優(yōu)點(diǎn)，但由于斜度的影響，受力特點(diǎn)與正橋也有較大的不同，其受力狀態(tài)分析十分復(fù)雜。針對(duì)不同斜交角的斜交空心板梁橋進(jìn)行有限元分析，運(yùn)用MIDAS/Civil建立有限元模型，理論分析斜交空心板梁橋荷載橫向傳遞規(guī)律，為橋梁的承載能力檢測(cè)與評(píng)定中荷載試驗(yàn)的控制截面選擇提供理論依據(jù)，在實(shí)際工程運(yùn)用中具有參考價(jià)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
