摘要
对抛物线、圆弧以及悬链线拱轴线在不同荷载作用下进行数值模拟,得出拱的压力线与其荷载条件以及线形有直接关系,给出不同荷载作用下拱结构的选形依据。
Based on the numerical simulate of parabolic,circular arc and catenary arch bridge axis on different load conditions,give the result that there is a direct relationship between the pressure line of arch and the load condition as well as the line shape,and provides the basis for the selection of arch structure on different load conditions.
