Force Path Analysis of Ballasted Jointless Bridge Turnout

Force Path Analysis of Ballasted Jointless Bridge Turnout

The action between bridge and ballasted jointless turnout on bridge is reversible. To locate the force path between them,the model of a jointless turnout on a 4×32 m continuous beam were calculated and analyzed. Also analyzed were factors of influence,such as：temperature increment,longitudinal pier...

Zusammenfassung:The action between bridge and ballasted jointless turnout on bridge is reversible. To locate the force path between them,the model of a jointless turnout on a 4×32 m continuous beam were calculated and analyzed. Also analyzed were factors of influence,such as：temperature increment,longitudinal pier stiffness,ballast resistances,and turnout and bridge layouts.
