Keywords: conventional railway platform, interlayer, axial displacement, double integration, acceleration data, axle weight influence.

Summary

The main goal of this paper is to show a valid method to filter and double-integrate acceleration data from a piezo-electric accelerometer installed in conventional railway platforms. The experimentation site involved is located in the region of Lille (northern France). Prospection tests were carried out at this site, including boreholes to a depth of 10m and Panda tests (dynamic cone resistance) to a depth of 1.2m. Accelerometers were installed in the interlayer of the platform. Acceleration data was recorded during the circulation of different types of train. These acceleration signals were then double-integrated in order to obtain the velocity and displacements within this layer. Different filters were applied to obtain relevant displacement results. Comparisons were made regarding different axial weights corresponding to intercity, freight and TGV trains.
