<p>Even though geosynthetics are now a well-established discipline within geotechnical engineering, ingenuity continues to be significant in projects involving their use. This is probably because of the ability to tailor the mechanical and hydraulic properties ...

<p>Numerical methods combined with centrifuge tests are used to investigate the distribution and development of soil stresses and reinforcement tensile loads in geosynthetic reinforced soil (GRS) structures. In this study, system stability indicated by the ...

This study evaluates the formation of hydraulic barriers for secondary containment through the permeation of colloidal silica grout. A simplified infiltration model is presented to predict the downward movement of the colloidal silica grout into a soil layer, ...

This paper presents the results of an elastoplastic finite element back analysis of an excavation made on a saturated soft organic clay deposit in Rio de Janeiro, Brazil. The excavation was conducted as part of an urbanization program, in which artificial ...

A new centrifuge permeameter was developed with the specific objective of expediting the measurement of the hydraulic characteristics of unsaturated soils. The development, theoretical basis, and typical results associated with using the centrifuge permeameter ...

This paper presents the hydraulic characteristics of an unsaturated, compacted clay, including its soil-water retention curve SWRC and hydraulic conductivity function K function , determined using a new centrifuge permeameter developed at the University ...

This study includes an experimental investigation of the transient movement of water in unsaturated soil layers underlain by a geocomposite drainage layer (GDL) during cycles of infiltration and evaporation

This paper provides theoretical background, laboratory data and full-scale measurements useful in understanding the interaction between soils and geosynthetics under unsaturated conditions. It also includes an evaluation of the current state of knowledge regarding ...

<p>A database of 534 large-scale direct shear test results was assembled in this study to evaluate the interface shear strength between geosynthetic clay liners GCLs and geomembranes GMs . The tests were conducted between 1992 and 2003 by a single independent ...

The contribution of transverse ribs to the soil-geogrids interaction under pullout mode has been well documented. However, the contribution of transverse ribs to the soil-geogrid interaction under direct shear mode is, at best, unclear. Consequently, this ...
