| Abstract: | Appliying to finite element software ANSYS,a finite element model of the integral calculation model of seamless turnout-beam-pier is established by using the finite element method.Taking size 18 swing nose turnout as an example,factors influencing temperature force and displacement of the seamless turnout are analyzed .These factors are the layout of support of simply supported beam bridge beside the ends of continuous beam bridge and the layout of expansion joints.The results can be used to guide the design of seamless turnout on continuous beam bridge. |
