Pull-Out Resistance of Geogrid Reinforcements Khalid Farrag Geosynthetic Engineering Research Laboratory (GERL), Louisiana Transportation Research Center (LTRC), Gourier Road, Baton Rouge, Louisiana 70803, USA Yalcin B. Acar* Civil Engineering Department, Louisiana State University, Baton Rouge, Louisiana 70803, USA & Ilan Juran Department of Civil Engineering, Polytechnic University, 333 Jay Street, Brooklyn, New York, New York 11201, USA (Received 30 September 1991: accepted 25 November 1991) ABSTRACT Testing equipment, specimen preparation and testing procedures are presented for load-controlled and displacement-rate-controlled pull-out tests for geosynthetic reinforcements in granular soils. The influence of the test type, confining pressure, soil density, boundary conditions, and geotextile characteristics on pull-out load-displacement response of selected geogrids embedded in sand are evaluated. Implications for testing procedure and analysis are discussed. farrag1993.rar
