Cyclic Behaviors of Anisotropically Consolidated Gravelly Soils under Triaxial Condition: Effects of Sand Gradation Part of the Soil

What is it about?

Weathering leads to a wide range of particle sizes forming in nature, and the combination of each category of soil particles (silt, sand, and gravel) may result in different soil behavior during earthquakes to consider while designing foundations for buildings and structures. Previous studies have extensively evaluated the combination of silt and sand, but the combination of sand and gravel, known as the sand-gravel mixture, has received less attention due to certain laboratory limitations related to gravel-size particles (larger than 4.75 mm). This research examines the behaviors of two different sand-gravel mixtures under loading conditions that simulate a real earthquake on a laboratory scale. It finds that the arrangement of finer particles among coarser ones controls the overall behavior of sand-gravel mixtures under earthquake loadings.
