Deformation analysis of a geosynthetic material subjected to two adjacent voids

This paper presents a new model for analyzing the behavior of geosynthetic material subjected to two adjacent voids. A simplified form of interface friction generated between geosynthetic materials and soil is examined to facilitate the development of an analytical model, and the effectiveness of the model is discussed. A field test and numerical analysis are also introduced to verify the analytical model. Based on the developed model, the coupling effect generated by two adjacent voids and the influence of several geometric and material parameters on the behavior of geosynthetic materials are investigated to develop a deeper understanding of this issue. The limitations of the model are discussed, and practical recommendations and conclusions on means of controlling geosynthetic tension and strain above two adjacent voids are presented.
