Several approaches for the design of reinforced bases on karst areas

Reinforcing earth foundations with geosynthetic materials

“…D.G. Zolotozubov (2011) completed a series of experimental studies to prove that the most efficient method to improve soil properties of foundations in low-loaded structures (q≤35 kN/m 2 ) in case of their deformations is using single or double-layer reinforcement with an embedding depth of 1.0 m and normal tensile strength of at least 4000 kN/m in the longitudinal direction [6].…”

The Behaviour of a Reinforced Soil Mattress Spanning a Cavity Modelled in a Geotechnical Centrifuge

“…Wang et al (1996) reported that the use of reinforced soils for bridging cavities has been limited compared to other applications due to a lack of research in this area. However, many research institutions are presently carrying out investigations into the use of geosynthetics to facilitate construction in difficult ground conditions, include the prevention of ground falls and subsidence as reported by Ponomaryov and Zolotozubov (2013).…”

Deformation analysis of a geosynthetic material subjected to two adjacent voids

“…Localized voids may develop in landfills with the collapse of large, hollow objects (e.g., household refrigerators or large furniture items) or when waste in old landfills is poorly compacted when a new liner system is placed over the top of the old landfill during a landfill vertical expansion project (Spikula, 1997;Kuo et al, 2005). Similarly, sinkholes are often encountered in karst terrain during and after the construction of engineered embankments Galve et al, 2012;Ponomaryov and Zolotozubov, 2014). In fact, the existence of underground voids renders the use of geosynthetics dangerous, as these materials can undergo substantial changes in stress and strain levels when suspended over voids; substantial tensile stress and strain can be produced within geosynthetics subjected to the weight of the overlying soil.…”
