3. Parameters intrinsic to LRS and IRS issues
3.1 Soil reaction modulus
This parameter is the modulus of the track bed, evaluated on the basis of geotechnical data and the characteristics of the ballast beds under the track. It is used to determine the distribution of vertical forces on ties and sleepers, and consequently to assess their dynamic lateral resistance.
SCROLL TO TOP3.2 Track resistance
This parameter is essential for buckling studies on LRS and IRS. It is the basic law of behavior that constrains rail displacements and consequently causes...
