Cyclic Behavior Of Transitional Fine-Grained Soils In Northern Willamette Valley, Frank Jarman
Cyclic Behavior Of Transitional Fine-Grained Soils In Northern Willamette Valley, Frank Jarman
Civil and Environmental Engineering Master's Project Reports
As discussed within studies from Idriss and Boulanger (2008) and Bray and Sancio (2006), the undrained cyclic shear behavior of low-plasticity fine-grained soils will transition between liquefaction (sand-like behavior) to cyclic softening (clay-like behavior) over a narrow range of plasticity index (PI). Despite not being sufficiently understood, the cyclic behavior of low plasticity silts has become an increasingly important field of study due to the significant impact it has on ground deformations and infrastructure failure in areas that are seismically active. Laboratory tests were performed on soils by third party consultants on a site located in the northern Willamette Valley, …
The Influence Of Halloysite Content On The Shear Strength Of Kaolinite, Reka Katalin Gabor
The Influence Of Halloysite Content On The Shear Strength Of Kaolinite, Reka Katalin Gabor
Dissertations and Theses
The objective of this thesis is to determine the relative shear strengths of halloysite, kaolinite, synthetic mixtures, and local soils, to investigate the influence of halloysite content on the shear strength of kaolinite, and to explore the possibility that the strength properties of soil clays might be controlled by the relative content of their component minerals.
