“…In this context, experimental, numerical and analytical works were performed leading to the understanding of some of the mechanisms of the process of reinforcement. This type of reinforcement could be used in landfills (Feng and Lu, 2015), road (Galve et al, 2012;Huang et al, 2015) or railway .…”

“…In such an structure where subsoil may have voids or sinkholes, membrane effect often occurs along with soil arching (e.g., Giroud 1981;Kinney and Connor 1987;Giroud et al 1990;Wang et al 1996;Han and Gabr 2002;Rogbeck et al 2003;Briançon and Villard 2008;Abusharar et al 2009;Lu and Miao 2015;Feng and Lu 2015;Huckert et al 2016;King et al 2017). During a subsiding process, geosynthetic interacts with overlying soil: subsided soil deflects geosynthetic and is also prevented from sinking by the deflected geosynthetic at the same time.…”

“…Later, Villard and Briançon (2008) analyzed the relative slippage between soil and geosynthetic in anchorage area based on Coulomb friction law. Besides, Feng and Lu (2015) expanded its applicability to geosynthetic reinforcement over two adjacent voids. However, all the above methods ignored the vertical deformation of supporting soil in anchorage area, which may significantly influence the evaluation of anchoring effect of the geosynthetic in this area and then membrane effect (e.g., Yu and Bathurst 2017), especially for soft ground.…”

A membrane effect often occurs in geosynthetic-reinforced structures, where subsoil may have voids or sinkholes. An analytical model is proposed to estimate membrane effect of a geosynthetic reinforcement subjected to localized sinkholes. The upper interface friction in the subsided area and vertical deformation of supporting soil in the anchorage area are considered simultaneously. The maximum geosynthetic strain and maximum surface settlement, serving as key design points, can be determined. Based on the proposed method verified using a full-scale experiment, a parametric study is conducted. The results show that ignoring upper interface friction results in significant undervaluation of maximum geosynthetic strain, and ignoring vertical deformation of supporting soil leads to obvious undervaluation of maximum surface settlement. A practical design framework is also proposed and it is an applicable tool for preliminary design of geosynthetic-reinforced structures, especially for cases with soft ground.

“…Some researchers (Li and Rowe, 2008;Ariyarathne and Liyanapathirana, 2015;Feng et al, 2015;Rowe and Liu, 2015;Yu et al, 2016;Zhang et al, 2016) have found that the geosynthetic reinforcement is significant in load transfer platforms. The geosynthetics can enhance load transfer efficiency and diminish differential settlements.…”
