Available in PDF, EPUB and Kindle. Book excerpt: Nonlinear large deflection finite element analyses of a fabric reinforced embankment on muskeg were performed to predict fabric tension and the effect of fabric stiffness on embankment deflections. The predicted fabric tensions were compared with the results of a sliding block analysis, and show this simple analysis requires further correlation to develop its applicability. Predicted fabric tensions increase directly with embankment deflection and fabric stiffness. Construction live loads produce the greatest embankment deflections and fabric tensions. Time and temperature effects were not considered. For the fabric stiffnesses studied, the presence of fabric does not significantly affect embankment deflections predicted by the finite element model. The beneficial effects of fabric reinforcement noted in field installations may result from the fabric providing continuity to the real embankment that is assumed in all the finite element analyses.

Available in PDF, EPUB and Kindle. Book excerpt: High strength geotextiles have allowed construction of embankments on soft soil foundations that will not support a man walking or support of conventional construction equipment. High strength geotextiles coupled with plastic strip drains have virtually eliminated the use of sand drains in the consolidation of soft clay deposits. This report describes a number of case histories of geotextile fabric-reinforced embankments constructed on very soft foundations in both Europe and the United States. The fabric-reinforcement philosophy for embankment design and construction developed by the US Army Corps of Engineers is presented in this report. Use of the design and construction techniques and methodology described in this report represent the latest state of the art for geotextile fabric-reinforced Embankment constructed on soft foundations.

Download or read book Selection of Geotechnical Fabrics for Embankment Reinforcement written by T. Allan Haliburton and published by . This book was released on 1978 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twenty-seven commercially available petrochemical-based geotechnical fabrics and one fiberglass fabric were tested and evaluated for suitability as reinforcement in an embankment test section to be constructed on soft foundation at Pinto Pass, Mobile Harbor, Alabama by the U.S. Army Engineer District, Mobile. Both woven and nonwoven fabrics were evaluated. All fabrics were subjected to initial testing in uniaxial tension and fabrics meeting or exceeding project sponsor-established strength criteria were subjected to additional testing for determination of creep behavior, soil-fabric frictional resistance, and effects of immersion and water absorption on developed tensile strength. The effects of specimen width and testing strain rate on uniaxial tension test results were also investigated. Four woven geotechnical fabrics plus the woven fiberglass fabric were found to meet or exceed required tensile strength criteria: Nicolon 66475, Nicolon 66186, Polyfilter-X, Advanced Type I, and Bay Mills 196-380-000 (fiberglass). Both Nicolon materials were found to have minimal creep tendency and strength loss after soaking. Bay Mills 196-380-000 had zero creep tendency and was not tested for soaking strength loss. Minimum soil-fabric frictional resistance for all five fabrics approximated soil alone behavior for a loose relative density condition. All five fabrics were recommended for consideration by the research sponsor for use as embankment reinforcement in test section construction. (Author).
