Performance test for Geosynthetic-Reinforced Soil including effects of preloading. (Recent Publications).Publication No. FHWA-RD-01-018A study was undertaken to investigate the behavior of Geosynthetic-Reinforced Soil (GRS GRS Graduate School (universities) GRS Great Red Spot (feature of Jupiter) GRS Gender Reassignment Surgery GRS Gamma Ray Spectrometer GRS Graduation Rate Survey GRS General Records Schedules ) masses under various loading conditions and to develop a simplified analytical model for predicting deformation characteristics of a generic GRS mass. Significant emphasis was placed on the effects of preloading. To conduct the study, a revised laboratory test, known as the Soil-Geosynthetic Performance (SGP SGP Singapore (ISO Country code) SGP Schering-Plough (stock symbol) SGP Stability and Growth Pact SGP Southern Great Plains SGP Staatkundig Gereformeerde Partij SGP Speedway Grand Prix ) test, was developed. The test is capable of investigating the behavior of a generic GRS mass in a manner mimicking the field placement condition, and soil and geosynthetic reinforcement are allowed to deform in an interactive manner. A series of SGP tests were performed. Different soils and reinforcements were employed, and the soil-geosynthetic composites were subject to various loading sequences. Correlations between the results of SGP tests and full-scale GRS structures were evaluated. It was found that the degree of reduction in settlement due to preloading could be assessed by the SGP tests with very good accuracy. Finite element analyses were performed to examine the stress distribution in the SGP test. The importance of using small reinforcement spacing was evidenced by the stress distribution. A Simplified Preloading-Reloading (SPR spr Spring SPR Strategic Petroleum Reserve SPR Surface Plasmon Resonance SPR Suomen Punainen Risti SpR Specialist Registrar (UK doctor who supports a consultant) SPR Society for Psychical Research SPR Stop Prisoner Rape ) analytical model was developed to predict the deformation characteristics of a GRS mass subject to monotonic monotonic - In domain theory, a function f : D -> C is monotonic (or monotone) if for all x,y in D, x <= y => f(x) <= f(y). ("<=" is written in LaTeX as \sqsubseteq). loading and preloading/ reloading Reloading A term lenders commonly use to refer to the habits of borrowers taking out loans to repay the balance on other loans. Often reloading is done to take advantage of lower interest rates offered by other loans, and potential tax benefits. . The SPR model was shown to be able to accurately predict the results obtained from the SGP tests and numerical analysis of automated plane strain reinforcement tests.
