Laboratory Simulation of Seasonal Wetting-Drying Cycles on Geosynthetic-Reinforced Clay Slopes and Embankments

摘要

This paper presents the development and commissioning of a laboratory testrnequipment to investigate the performance of geosynthetic-reinforced clay subjected tornseasonal wetting-drying cycles. This work is a part of an on-going research projectrnthat will develop embankment stabilization techniques using geosyntheticrnreinforcement for highway interchanges and bridge sites. It focuses on how tornimprove the reliability of the design of geosynthetic-reinforced soil structures usingrnmarginal or non-select fills (clays and silts) by incorporating environmentallyinducedrnloading (wetting-drying in clays and freezing-thawing in silts).
