Abstract
Railway embankments using crushed rock from tunnel construction are widely implemented to reduce constructioncosts. However, if residual settlement continuously occurs beyond allowable settlement after track construction,maintenance for railway safety operation may expend great resources of cost and time. Research on rock fillembankments has mainly been performed in the areas of dams and roadways, while researches in railway field weremostly studied for compaction characteristics and settlement behaviors in laboratory. There are very few research resultsusing field measurement to estimate long-term behavior of railway embankments. In this study, field measurementswere conducted on over-20-meter-high railway embankments for which large and long-term residual settlement aftertrack construction were expected. Using the back-analysis technique, creep parameters for the Kelvin Body Model areproposed and a numerical method to estimate the amount of and time for residual settlement are also proposed in thisresearch.
