2D and 2.5D Responses of Long Underground Tunnels to Moving Train Loads: A Comparison Study,approach saves a huge amount of computation time, due to the use of relatively smaller system matrices. But the 2.5D approach is more realistic in that it can cope with wave transmission along the tunnel axis.

Spatial Rotations of Principal Stress Axes in Infrastructures on High-Speed Railway,ctures on high-speed railway under moving impulse pressures are investigated. The results indicate that the principal stress axes rotate in XY, XZ and YZ plane synchronously and continuously, the rotation in YZ plane predominate for embankment, embankment-bridge transition zone and tunnel. The rotat

Field Measurement and Analysis of Ground Vibration Induced by High-Speed Train,om the track centerline, but a vibration boom occurs at the distance of 12 m. The effect of both P and S waves cannot be neglected in the vicinity of the track, while R waves begin to dominant beyond the distance of 15 m. In addition, an important frequency in the acceleration spectrum of the ground

Dynamic Shakedown Analysis for Anisotropic Material Under Traffic Moving Loading,increases towards the Rayleigh wave speed of the pavement for isotropic half-space system. For cross-anisotropic half-space system, Poisson’s ratio only leads to negligible effect on shakedown limit. Furthermore, the shakedown limit rises with the increasing cohesion ratio ...., but it reaches maxim

Discrete Element Simulation Study of Contact Pressure Distribution Between Sleeper and Ballasts,last layer follows a double-peak pattern. This pressure distribution is compatible with the results of an experimental research in railway sleeper. Although the model still needs to be elaborated and calibrated further, this work adds to the understanding of the behavior of sleepers used in service.
