Field data are reported that describe the load–strain–time relationship of geogrid reinforcement in a reinforced soil structure. The data are for a period exceeding 5 years and reveal a continued strain in the reinforcement, which occurs at nearly constant load. The response to loading is attributed to creep of the polymeric material. A comparison of the field data with laboratory isochronous load–strain curves, from rapid loading creep tests performed at a temperature similar to the mean annual temperature in the backfill soil, shows the curves describe very well the magnitude of creep strains observed in the field. Implications of the load–strain–time performance data are assessed with reference to the use in design of a tensile strength established from the rapid-loading creep test and wide-width strip test. The need to clarify, in design of polymeric reinforced soil structures, between a safe and allowable tensile strength is emphasized. Key words : reinforced soil, geogrid, creep, tensile strength, strain.

Reinforced soil (RS) is a composite material built of a soil matrix reinforced with other materials such as metal strips, geosynthetics etc. RS has been increasingly used in civil engineering, either as a cheaper alternative to classical geotechnical structures, or as an independent technical solution. The aim of this article is to present a state-of-the-art review concerning the mechanics of RS and mechanics of RS structures. Research on both subjects was initiated by pioneering works of H Vidal in the 1960s. First, a brief introduction is presented followed by a review of mechanical models of RS, including rigid-plastic, elasto-plastic, and rheological. Then, the methods of analysis of RS structures are discussed. These methods include the limit states approach, determination of stresses, creep etc. Some research needs are also outlined. The article is presented in the form of a tutorial review which also includes a state-of-the-art review and a basic bibliographical survey. There are 200 references.
