Short summary
Geosynthetic (RG) are used to reduce subsidence. This paper focuses on the use of largescale physical modelling to study the subsidence mechanisms and to estimate the RG efficiency. The results have shown that the RG reduced the subsidence. The deformation of the RG and the surface settlement depend both on the soil type and overload intensity. The experimental results are compared to analytical solutions. The results shown that the analytical models can predict the behaviour of reinforced soil.
