...M. M. Omran; A. M. Ahmed; R. Adel; I. S. Fahim; E. S. Bakhoum; S. S. AbdelSalam Expanded Polystyrene ( EPS ) is widely used in geotechnical applications, where its durability depends on geomembrane protection. The aim of this study was to develop a new eco-friendly nanocoating for EPS, that can...

...H. M. G. Eldesouky; R. W. I. Brachman A new method, direct stress relaxation, was developed, verified and applied to calculate local geomembrane stress from local strain induced by gravel particles. The method utilizes the fading memory concept whereby the deformation path is taken to have a minor...

...G. Xu; J. Shi; Z. Liu; H. Zhang; Y. Gu Geotextile and geomembrane are widely used in landfill liner systems, but the relationship between geomembrane roughness and geotextile/geomembrane interface residual shear strength remains to be studied. In this paper, by using a large-scale ring shear...

...T. Li; D. Sun; P. Ni; Z. Chen; L. Wang Geomembrane (GM) is a kind of cost-efficient material for pollutant barriers in landfills, while defects can occur during the installation or service periods, resulting in a mixed-type boundary condition (MTBC) at the top surface of the underlying soil layer...

...G. Xu; J. Shi Geotextile/textured geomembrane (GTX/GMBT) liner at the bottom of the landfill will be exposed to ultraviolet (UV) radiation after installation and before being put into use, but the interface shear behaviour has not yet been studied. In this paper, based on laboratory UV accelerated...

... and properties of both the geosynthetic and the soil. This paper introduces a machine learning approach, specifically a random forest algorithm, for predicting interface friction angles. The dataset comprises 495 interfaces involving geomembranes and sand, with 14 influencing parameters recorded for each...

...J. Fan; R. K. Rowe Leakage and erosion of a soluble subgrade overlain by a geomembrane with a 70-mm-long slit defect is examined. The subgrade (gypsum) solubility and its rate of dissolution from a solid state in contact with various solutions are investigated. In the absence of flow, the rate...

...J. Qiu; Y. He; D. Song; J. Tong Analytical solutions for the transport of contaminant through a 1D triple-layer composite liner system consisting of a geomembrane (GMB), a geosynthetic clay liner (GCL) and a compacted clay liner (CCL) under non-isothermal conditions are derived using...

...J. P. Giroud; H. Plusquellec This technical note complements a published lining evaluation for a canal in Egypt. Concrete and geomembrane linings are compared regarding leakage control and cost. Published data on leakage with concrete and geomembrane linings are reviewed, and analyses show...

...M. Samanta; R. Bhowmik; H. Khanderi The seismic stability of geosynthetic structures incorporating soil-geomembrane interfaces depends largely on their response to dynamic loads caused by earthquakes or traffic. The present study investigates the dynamic shearing response of sand-smooth geomembrane...

.... To date, shear test data on composite liners that contain more than two geosynthetics are limited. This paper presents an experimental study of the interface shear behaviour of a multilayer geosynthetic liner consisting of a drainage geocomposite (GC), a textured geomembrane (GMB), and a needle-punched...

...B. A. Marcotte; I. R. Fleming High localized strain in geomembranes caused by indentations from coarse, uniform drainage aggregate is associated with long-term stress cracking and has been widely studied. A number of large-scale lab tests were carried out with direct measurement of the distribution...

..., geomembranes need to be selected carefully as their resin type will dictate their performance. Preliminary hydraulic conductivity test results using unamended and activated carbon amended geosynthetic clay liners indicate they can play a role in minimising the migration of PFAS, although the tests are still...

...K. V. N. S. Raviteja; B. M. Basha Geomembrane liners that are installed in anchor trenches may experience pullout failure when the applied tensile stress exceeds the allowable strength of the liner.
