<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 ...
Reference: GEOTECHNICAL ENGINEERING STATE OF THE ART AND PRACTICE
<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 ...
Reference: Geosynthetics International, February, Vol. 19, No. 5, 2012
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, ...
Reference: Journal of Environmental Engineering, ASCE, Vol. 137, No. 6, June, 2011
<p>A narrow mechanically stabilized earth (MSE) wall is defined as a MSE wall placed adjacent to an existing stable wall, with a width less than that established in current guidelines. Because of space constraints and interactions with the existing stable ...

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 ...
Reference: Journal of Geotechnical and Geotechnical Engineering, ASCE, Vol. 136, No. 8, August, 2010
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
Reference: Canadian Geotechnical Journal, Vol. 47, No. 11, November, 2010
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 ...
