Recently, slab track systems have arisen as a safer and more sustainable option for high speed railway infrastructures, compared to traditional ballasted tracks. Integrating Wireless Sensor Networks within these infrastructures can provide structural health related data that can be used to evaluate their degradation and to not only detect failures but also to predict them. The design of such sy...

Railways employ a range of different railway track forms. Here, ballasted design is compared to three slab solutions. The designs are using both life cycle analysis (LCA) and methodology for simulation three-dimensional vertical dynamic vehicle–track interaction, which has been verified versus field measurements. interaction between vehicle simulated in the time domain an extended state-space v...

In this study, the performance of shred tire mixed with railway subgrade is evaluated to reduce environmental vibrations caused by trains’ passage. Since incorporating the Shred Tire seeds in soil affects on its shear strength and deformability parameters so, the first stage of the study was allocated to conducting a series of laboratory tests such as the unconfined compression test, and CBR an...

The dynamical responses of railway track has been carried out by different ways. In this work, developing an analytical model for the ballasted which includes two rails connected to sleeper, a fast method calculated dynamic is presented. rail modelled as infinite beams posed on periodically supports are rested viscoelastic foundation. We consider equation in steady-state subjected moving loads....

investigations on vibration behaviors of railway track systems were attempted in this research. this was made by conducting a comprehensive field investigation into the free vibration of track systems and response of tracks to train moving loads. in-situ modal analysis was used in a railway track field as an efficient method of investigating dynamic properties of railway track systems. natural ...

In this work, the vertical motion of a simply supported railway bridge which is subjected to circulation high speed trains was studied. A system consisting two-layer beam considered model dynamics structure. The upper represents rails with sleepers and lower deck. These two beams are coupled through distributed nonlinear springs that ballast action. characteristics these elements were identifie...

Railway lines typically use traditional sloping embankments as the principal means of track support. However, Geosynthetically Reinforced Soil (GRS) systems have gained popularity alternatives to conventional embankments, particularly for high-speed in Japan. This system requires less ground stabilization/improvement and land take than due its smaller base area. research investigates immediate ...
