| Abstract: | Summarizing the conclusions of computation in available literatures and analyzing synthetically actual experimental data,the paper established an interaction model of beam and rail,and by adopting FEM and a program compiled by C language,this paper studied and calculated the rupture forces in the continuously welded rails(CWR)on a specially-designed simply-supported reinforced concrete bridge,and the distribution of rupture forces in rails as well as the law of their transmission to bridge piers and abutments. |

| Keywords: | urban rail transit specially-designed bridge rupture force calculation |
