Figures in eps/tif format
Data for Figures 1, 7, 9, 10, 12

The figures are as follows:

Fig. 1  Comparison of settlement results obtained at 100,000 cycles using the equations in Table 1. For each box, the
central mark indicates the median, and the bottom and top edges of the box indicate the 25th and 75th percentiles,
respectively
Fig. 2 Form of the relationships between track settlement and number of load cycles given by the Okabe equation
(Equation (1), [38]) and a modified version proposed in [39, 40].
Fig. 3 Settlement rate according to (a) Eq. 5 and (b) Eq. 6 [42] vs sleeper-ballast interface force or pressure
Fig. 4 Variation of settlement predictions with trackbed stiffness using the Fröhling equation within (-)_and without
(--) the defined limits.
Fig. 5 Typical calculated stress-strain response and corresponding evolution of threshold stress in a calculation using
the semi-analytical model.
Fig. 6 General methodology used to iteratively link together the short-term and long-term ballast behaviour [12].
Fig. 7  Trackbed stiffness distribution, case study 1: original distribution and modified distribution to limit the
trackbed stiffness to between 60 and 132 MN/m
Fig. 8 (a, c) Evolution in time of settlement below sleepers, (b, d) distribution of ballast forces for Class 91 vehicle and
(e, f) settlement predictions against trackbed stiffness according to Fröhling’s equation and the semi-analytical
settlement model, respectively
Fig. 9  Comparison of mean settlements calculated with number of load cycles for (a) Class 91 and (b) freight vehicle
Fig. 10  Trackbed stiffness distribution in case study 2.
Fig. 11 Comparison between trackbed stiffness distributions; (a) case study 1 and (b) case study 2.
Fig. 12  Comparison of mean settlement evolution calculated using the Guérin and Sato equations and the semianalytical
model for (a) Class 91 and (b) freight vehicle.
