“…11(b). In full-scale model tests, the dynamic stresses measured below the concrete slab in ballastless tracks could vary in the range 13-20 kPa (Bian et al 2014). These stresses are significantly lower compared to those observed in this ballasted field study (250-400 kPa), which could obviously be attributed to the discrete sleepers (ties) spaced typically at 0.6 m intervals (i.e., discontinuous supports unlike a continuous track).…”

“…A matching procedure is thus proposed based on the fact that the maximum surface displacement of the substructure equals the maximum deflection of the beam on an equivalent Winkler's foundation. The matching procedure has been validated by comparing the pressure distributions at design situations to those measured in field and model tests of Bian et al (2014). In the present study, a three-layered substructure consisting of an antifrozen layer, a prepared subgrade layer and subsoil with great depth is considered.…”

“…Thus, the soil pressure cells under different load stages could be calibrated under close condition in the Chamber. With this calibration, the pressure cell can give satisfactory performance under cyclic loading (Bian et al, 2014) and the errors were expected to be within 25%. …”
