High-speed trains induce a small level of permanent settlement within their supporting railway track and ground during passage. The settlement grows over time, but the degree of settlement varies along the track depending upon geographical changes in ground conditions. The variation in settlement along the track is the most important factor in determining the strategy for maintenance; when settlement limits are exceeded, the track must be closed to rail traffic and expensive reconstruction work must be undertaken. During this project, you will explore and develop novel geophysical approaches that can provide both non-invasive and cost-effective pseudo-geotechnical survey data. Working closely with the University of Leeds Infrastructure Testing Facility at the Institute for High-Speed Rail and System Integration, you will perform a suite of tests at purpose-built test track-beds. The results will be used to devise a novel geophysical methodology to predict or map differential settlement levels.
