摘　　要：文章运用有限元程序对三线铁路预应力混凝土连续箱梁桥进行了模拟,分析了三线铁路荷载作用下箱梁的受力特性及在各种荷载工况下荷载横向分布规律,给出了荷载横向系数的实用值。This paper presents an study using a finite-element program in which a continuous bridge prototype of three lines and prestrssed concrete, each subjected to various loading conditions, are analyzed for the rule of lateral load distribution. The practical value of the lateral load distribution factors is presented.
