Modelling of critical speed of railway tracks on a multi-layered transversely isotropic saturated ground
TL;DR: In this paper , the authors proposed an analytical model to analyze the effect of the transverse isotropy of ground on the critical speed of railway tracks on stratified saturated soils by using the Biot's theory.

Finite Element Method Accuracy for Wave Propagation Problems
Roger L. Kuhlemeyer,John Lysmer +1 more
TL;DR: In this article, the authors presented the results of a study concerning the accuracy of displacements caused by a single, harmonic, one-dimensional elastic wave propagating through a finite element mesh.

High-speed railway lines on soft ground: dynamic behaviour at critical train speed
Christian Madshus,Amir M. Kaynia +1 more
TL;DR: In this paper, it is shown that large dynamic amplifications appear in the dynamic response of the rail/embankment/ground system as the train speed approaches an apparently critical value.

Generation of Ground Vibrations by Superfast Trains
TL;DR: In this article, the authors studied ground vibrations generated by superfast trains taking into account the contribution of each sleeper of the track subjected to the action of the carriage wheel axles, and showed that a very large increase in vibration level may occur if the train speed exceeds the velocity of Rayleigh surface waves in the ground.

Application of the failure state in undrained simple shear to the shaft capacity of driven piles
Mark Randolph,C. P. Wroth +1 more
TL;DR: In this paper, a critical review is made of the variation of undrained shear strength with the value of intermediate principal stress, so that the strength in plane strain conditions may be compared properly with the values measured in triaxial compression.

A theoretical study on the influence of the track on train-induced ground vibration
TL;DR: In this paper, a theoretical model for train-induced ground vibration propagation is presented based on the track and a layered ground and the results of the responses of the ground and track to a moving harmonic or quasi-static load on the rails are given.
