Abstract

Deformations of bridge deck ends on abutment can cause extreme deformations on track. Especially, since slab track was fixed onto the bridge deck slab on concrete slab track installed bridges, deformations of bridge deck ends directly affect the slab track behavior, and thus these interactions can bring about the premature failure of rail fastenings or other deteriorations to lower the serviceability. In this study, a foreign standard to evaluate forces on track components caused by the track-bridge interactions and the behavior of bridge deck ends was investigated and for real scale bridges. It was found that rail support spring coefficients, as well as toe loads, support spacing were very important parameters.
