摘要:
文章以成昆铁路某三线桥采用的（52+88+52）m单箱双室、变高度、变截面预应力混凝土连续梁为研究对象，运用ANSYS有限元软件建模计算，分析了铁路三腹板连续梁三道腹板的受力，对比三道腹板所受的纵向弯曲正应力和竖向剪应力的大小，并研究其在三道腹板中的分布规律和沿梁长的变化情况。根据分析结果，总结出该梁三道腹板所受的纵向弯曲正应力和竖向剪应力的变化规律，提出梁体截面优化措施，可为类似连续梁三道腹板优化设计提供参考。
Abstract:
In this paper,(52+88+52)m prestressed concrete continuous girder with single box, variable height and variable section used in a three-line bridge on Chengdu-Kunming railway is taken as the research object, by using ANSYS finite element software, the stress condition of webs in the three-web continuous girder is analyzed. The longitudinal bending normal stress and vertical shear stress are compared, and the regularities of distribution of both stresses in three webs and the variation of these stresses along the girder length are also discussed. The numerical results demonstrate that, the regularities of variation of longitudinal bending normal stress and vertical shear stress are concluded, and optimization measures of beam body section are put up, the results can be served as a reference for the optimism design of webs in the railway continuous box girder.
