  1. Pore-water pressure accumulation under dynamic loadings

    Jung, HyunilUniversity of Illinois Urbana-Champaign2025

    … analyses were conducted and the level of excess pore-water pressure accumulated during closely spaced earthquakes was investigated. Results of laboratory triaxial compression tests, drained, undrained, and cyclic direct simple shear tests on loose sandy tailings were used to calibrate the soil …

  2. The Behavior of Pore Water Pressure in Cohesive Subgrade Soils

    Lee, JangguenThe Ohio State University2003

    This research focuses on the behavior of pore water pressure in subgrade cohesive soils under Falling Weight Deflectometer (FWD) tests. The deflection of a pavement structure largely depends on the deformation of subgrade soils, which is in turn dependent upon soil stiffness. Soil stiffness can be …

  4. Pore water biogeochemistry and trace metal dynamics in deep intertidal flat sediments

    Beck, MelanieUniversität Oldenburg

    Biogeochemical processes were studied in deep pore waters at different locations in the backbarrier area of Spiekeroog Island, Germany. A multilevel in situ pore water sampler was developed, which allows pore water sampling down to 5 m sediment depth. Sulphate, DOC, and nutrients were studied for …
