“…In this case, other more convenient approaches are necessary, for example a numerical model developed by Laghrouche in [35] can be used. This model has been compared with the semi-analytical approach for a semi infinite medium by Lefeuve-Mesgouez et al in [36] and can be used in future developments to study solutions to specific vibration problems such as: sites with trenches, inclusion of damping layers or the presence of concrete columns under or near the track. Also in our approach, the ground is modelled as an isotropic and homogeneous linear elastic medium with a material dissipation by means of a hysteretic damping hypothesis.…”

In the North West of France, more particularly in the region of the Somme Bay, where the ground is constituted mainly of peat, observation of the surface of the soil near railway tracks has revealed high levels of displacement. This paper, contains a prediction model and diagnosis of vibration near the track. A model of a railway track on layered ground subjected to a moving train has been built and the calculation method uses Fourier transform formalism for a semi-analytical solution in the wave number domain. It includes all elements of the track and allows a parametric analysis of its different elements and evaluation of vertical displacement according to the speed, weight and composition of each train. The diagnosis has been performed with in situ measurements and with the aim of the validation of the model. A parameter study of the ground undertaken by seismic measurements shows a critical speed close to 100 m/s while the studied trains are moving with subRayleigh speeds. Measurements give us a lot of information about lateral and vertical acceleration on the soil's surface and parts of the track. For high speeds and freight trains, displacement reaches more than 10 mm.

“…1. The soil and load parameters of the literature [3] Fig.5 gives non-dimensional vertical displacement curves on soil surface for different load frequencies when k=1/3.As can be seen, frequencies have less impact on the maximal displacement amplitude of the center. Vertical displacements change in the form of damped oscillation along with the increase of x.…”

“…Sneddon [2] first studied the dynamic response of the elastic half space soil in the condition of plane strain under uniform moving line loads. Lefeuve-Mesgouez et al [3] used potential function and the Fourier transform to solve the dynamic response problems of single-phase elastic half space under plane strain state in the vicinity of a high-speed moving harmonic strip load. Honglei SUN [4]used the semi analytical method to solve the dynamic response of the transversely isotropic poroelastic half-space soil medium.…”

Abstract. Two-dimensional dynamic response of orthotropic media under rectangular coordinate system was studied. With displacement component of the basic unknown quantity, the dynamic equations were drawn for orthotropic media, and the dynamic responses in time domain for orthotropic elastic media under harmonic loads was derived by means of Fourier transform. Vertical displacement curves of the calculated point due to different depth, different soil parameters and load frequencies are researched.

“…Krylov [16], Lefeuve-Mesgouez et al [17], Ju [18], Ju and Lin [19]). In the foregoing situations, the moving mechanical / thermal load may produce severe deformation and temperature rises in a thin zone near the contact zone, and therefore may cause excessive wear and even cracking near this zone.…”

Since there is an analogy between the steady-state theories of thermoelasticity and poroelasticity, the present results carry over to the latter case directly.
