Pullout and Creep of Geosynthetics in a Soil Matrix
The purpose of this research is to design and fabricate a Large Scale Pullout/Creep Device (LSPCD) to isolate and evaluate the parameter which affect the restrained pullout and creep properties of extensible earth reinforcement. The analyses in this report focus on the interaction of a polyester geogrid material in a cohesionless soil under a variety of boundary conditions. The term 'geosynthetics' refers to the broad spectrum of materials which, when used in conjunction with soil or rock materials, improve the newly formed composite system. Geosynthetics are further divided into three areas; geomembranes, geotextiles and geogrids. Factor influencing the creep and confined tensile strength of geosynthetics in soil are evaluated. Current state-of-the-art practices and methods used to evaluate confined creep and tensile strength are investigated. An LSPCD, which improves upon previous instrumentation, is designed and results of analyses are presented. A complete laboratory analysis of the soil media is presented to further quantify results.
