Study the Stability of Railway Tracks Under Earthquake Loading- the case of Syrian railway track

Abstract

In this research, a finite-element (FE) model including the track superstructure and substructure components was developed for seismic analysis of railway track in Syria by using abaqus feature, In the developed model, the beam elements were used to define rails and sleepers as

components of track superstructures. Moreover, a series of lumped masses with connectors was considered for modeling the ballast, sub ballast, and subgrade as track substructure components. Every connector has stiffness and damping factor, in order to validate the FE model, the results of seismic numerical analysis were compared with the outputs of a lateral reference study, the purpose of this study is to investigating the stability of Syrian railways under seismic excitation.
