...K. Kazemi; M. R. Arvin; N. Hataf; A. Khademhosseini This study examines the behaviour of square footings located on unreinforced, single-, and double-layer geocell-reinforced sand slopes through a series of reduced-scale model tests. Contributing factors such as the distance between the footing...

... slopes. Laboratory tests were conducted by varying parameters such as embedment ratio, length and number of reinforcement layers, and edge distance from slope crest. A numerical study using finite-element analysis (PLAXIS 2D, version 9.0) was also carried out to verify the model test results. The size...

...C.-N. Liu; R. B. Gilbert This paper presents graphical solutions for estimating geosynthetic loads in geosynthetic–soil layered systems on slopes. The graphical solutions are based on a simple analytical approach that maintains strain compatibility and force equilibrium. The solutions are presented...

...J.P. Giroud; J.G. Zornberg; J.F. Beech Liquid collection layers used in landfills often comprise two sections with different slopes. Typically, one of the slopes is much steeper than the other one. The steeper slope is generally the downstream slope in a landfill cover and the upstream slope...

... exhibits an increase in peak shear strength of approximately 13% per log cycle of the shear rate. Therefore, the selection of a shear displacement rate is important for unreinforced geomembrane-backed GCL/textured geomembrane interface shear tests. Geosynthetic clay liner Strength Stability Slope...

...J.P. Giroud; N.D. Williams; T. Pelte; J.F. Beech This paper presents a method based on limit equilibrium to evaluate the stability of geosynthetic-soil layered systems on slopes. Examples of geosynthetic-soil layered systems constructed on slopes include liner systems used in landfills, liquid...

...J.P. Giroud; R.C. Bachus; R. Bonaparte This paper presents an analysis of the stability of geosynthetic-soil layered systems constructed on slopes when water is flowing along the slope. Equations are presented for the factor of safety of infinite slopes as well as slopes of finite height...
