SINKHOLES BENEATH A REINFORCED EARTHFILL, A LARGE SCALE MOTORWAY AND RAILWAY EXPERIMENT

A geosynthetic preventive reinforcement system was tested under railway line and road bedding layers in order to propose solutions to the risk of localized sinkholes related to the rise of subsurface cavities under the road or railway embankment. Full-scale experiments were conducted on an instrumented experimental site. The formation of cavities 2 and 4 meters in diameter was simulated under the fill material reinforced with geosynthetic sheets of different stiffness characteristics. Deflection, displacement and strain measurements were taken continuously on the geosynthetic sheet and within the fill material. The experimental results presented illustrate the merits of the proposed technical solution.
