Investigating permeability in the behavior of surface foundations created on soils with geosynthetics and seismic performance of GRS walls (review)

Reinforced soil foundation with geosynthetics (GRS) can improve the bearing capacity of the foundation and reduce the foundation settlement, which has been widely used for the treatment and improvement of soft soil foundation. In recent years, researchers have conducted many studies to show the effect of various factors on the load and settlement behavior of GRS foundations. In this study, the strengthening mechanisms of reinforced materials are first briefly stated, and then an overview of the history of planar geosynthetic reinforced foundations from the aspects of experimental studies, numerical simulations, and theoretical analyzes is provided. Finally, the current research trends of reinforced Pi and prospects for future study are discussed. Although research on the performance of GRS foundations has been extensively conducted, In the range investigated by the authors, which is believed to cover general fill soils and geosynthetic reinforcements, the creep rate of soils and reinforcements had little effect on the reinforcement load and the "double-wedge" deformation mode, but the stiffness of the reinforcement played an important role. . On these two answers the walls of the GRS. It was also found that the "two-piece" deformation mode could be constrained if a sufficiently long amplifier was used. The study shows that it is reasonable to investigate the reinforcement load of reinforced soil walls subjected to seismic loading without considering the previous long-term creep. Finally, a conclusion of this paper presents the results of numerical parametric study of simple geosynthetic reinforced soil (GRS) walls under real multidirectional ground motion shocks
