Performance Test for Geosynthetic-Reinforced Soil including Effects of Preloading

摘要

A study was undertaken to investigate the behavior of Geosynthetic ReinforcedSoil (GRS) 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 effect of preloading. To conduct the study, a revised laboratory test, known as the Soil-Geosynthetic Performance (SGP) test, was first developed. The test is capable of investigating the behavior of a generic GRS mass in a manner mimicking the field placement condition, and the 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.
