摘要

Most rail site investigations rely on dynamic probing and window sampling, rather than conventional boreholes, to cope with challenging timescales during night-time and weekend possessions. However, while these techniques are fast and relatively simple, they are limited in the subsurface materials they can investigate; often they cannot reach the required depths and the data they provide is of limited use.
