Abstract

Most geosynthetic materials exhibit rheological properties that lead to creep strain response when subjected to sustained loads, and consequently it is necessary to evaluate their long-term creep deformation before any real application. This paper presents the results of sustained loading tests conducted on large-scale geogrid soil reinforcement. The purpose of these laboratory tests was to identify the appropriate design parameters for geosynthetic-reinforced systems. The results of these tests demonstrate the continuous creep deformation characteristic of geogrid materials under constant sustained loading. The increase in the applied load led to a continuous increase in the amount and rate of the geogrid creep deformation. The data analysis method used in this investigation enabled the possibility of predicting the load-deformation-time behavior and the ultimate load of geosynthetic reinforcements.
