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)...

Soil solution chemistry, profile development, and mineral authigenesis in several western Oregon soils

Creator:: Glasmann, Joseph Reed
Abstract:: Clay mineral genesis was studied in soils representative of several different geomorphic surfaces in western Oregon, ranging in age from Pliocene-early Pleistocene to late Pleistocene. Soil solution studies, clay mineralogy, and soil raicromorphology were employed to provide evidence of clay mineral synthesis and interpret soil genesis. Soils at each study...

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...
