The dispersion of some amorphous and crystalline clays

Creator:: Hickman, John S.
Resource Type:: Masters Thesis

Clay mineralogy in relation to landscape instability in the coast range of Oregon

Creator:: Istok, J. D.
Abstract:: The mineralogy of soils involved in mass movement in Oregon's coast range was examined to determine relationships between clay mineralogy and landscape instability. The objectives were: 1) to determine what kind of materials constitute the less than 2μ fraction of soils involved in different categories of mass movement, and 2)...

Improvement in percolation of water thru soils having a high clay content and restricted drainage

Behavioral thresholds in mixtures of sand and clay

Creator:: Simpson, Daniel Corder
Abstract:: Nearly all soils are comprised of mixtures of coarse and fine particles. Behavior under mechanical and thermal loading of soil is strongly influenced (and in some cases, governed) by the ratio of coarse to fine particles. A better understanding of the fundamental behavior of soil mixtures will provide insight to...

Bearing capacity and immediate settlement of shallow foundations on clay

Creator:: Strahler, Andrew W.
Abstract:: Shallow foundations are extensively used to support structures of all sizes and derive their support from near surface soils. Thus, they are typically embedded up to a few meters into the soil profile. Designers of shallow foundations are required to meet two limit states: overall failure of the soil beneath...

Three-dimensional experiments and modeling of anisotropic clay

Creator:: Anantanasakul, Pongpipat
Abstract:: This dissertation presents the results of a research effort conducted to better understand the stress-strain, volume change, shear band formation, and strength characteristics of normally consolidated anisotropic clay under fully three-dimensional stress states. A series of consolidated drained true triaxial tests with a constant mean effective stress and constant Lode...
Resource Type:: Dissertation
Full Text:: had similar types of base clay and silt. The first soil had a silt content of 50% and clay content of

Characterization of hydrologic parameters and processes in shrink-swell clay soils

Creator:: Stewart, Ryan D.
Abstract:: Vertisols and other vertic-intergrade soils are found all over the globe, including many agricultural and urban areas. These soils are characterized by their cyclical shrinking and swelling behaviors, where bulk density and porosity distribution both vary as functions of time and/or soil moisture. In turn, alterations in physical soil parameters...
