| Abstract: | With the development of high speed railway anct urban rail transit system,turnout being built on bridge are inevitable, Continuous welded turnout on bridge is a key technique for developing continuous welded railway across sections, The model of jointless turnout on bridge is built up by using the finite element method, the forces and displacement of jointless turnout are computed, and the influences on jointless turnout of bridge structure are analyzed. The results can be used to guide the design and the maintenance of jointless turnout on bridge. |
