以湖南某特大桥为研究背景，用ANSYS对预应力混凝土变截面箱梁顶板中心横向预应力的工作宽度进行理论分析，得出横向预应力在顶板的工作扩散角，为设计预应力混凝土连续箱梁桥顶板横向预应力提供参考，对预防顶板纵向裂缝具有指导意义．分析张拉横向预应力后产生的泊松效应，为箱梁顶板预应力的张拉施工提供建议．

Taking a bridge of Hunan as research background , the transverse stress working width analysis of prestressed variable cross-setion concrete box-girder bridge by ANSYS is disussed and the transverse stress diffusion angle in the roof is achieved. Reference for the design of prestressed concrete continuous box-grider bridge roof transverse prestress is provided and guiding significance is given to the prevention of roof vertical cracks. The tensioned transverse prestress poisson effect is analyzed, and recommendations for the tension construction of the box girder roof prestressed are given.
