Analysis of the Influence of Cracked Sleepers under Static Loading on Ballasted Railway Tracks
The principal causes of cracking in prestressed concrete sleepers are the dynamic loads induced by track irregularities and imperfections in the wheel-rail contact and the in-phase and out-of-phase track resonances. The most affected points are the mid-span and rail-seat sections of the sleepers. Central and rail-seat crack detection require visual inspections, as legislation establishes, and i...
متن کاملInvestigation of the Influences of Track Superstructure Parameters on Ballasted Railway Track Design
The main design criteria of ballasted railway tracks include rail deflections, rail bending stresses, rail wheel contact stresses, sleeper bending moments and ballast sleeper contact pressures. Numerous criteria have been defined for the design of ballasted railway tracks owing to the various mechanical properties of track components and their complex interaction. Therefore, railway track desig...
متن کاملMoving Load Analysis on Skewed Railway Bridge
Recent developments in the field of high speed rail have heightened the need for improving of railway bridges under the passage of high speed trains. However, little attention has been paid to influence of significant parameters playing a key role in dynamic behavior of such bridges. This paper seeks to fill such a gap by carrying out finite element (FE) analysis on an existing railway bridge. ...

متن کاملPerformance of Shred Tire Mixed with Railway Subgrade in Reduction of Train Induced Vibrations
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...
