ASU Electronic Theses and Dissertations
This collection includes most of the ASU Theses and Dissertations from 2011 to present. ASU Theses and Dissertations are available in downloadable PDF format; however, a small percentage of items are under embargo. Information about the dissertations/theses includes degree information, committee members, an abstract, supporting data or media.
In addition to the electronic theses found in the ASU Digital Repository, ASU Theses and Dissertations can be found in the ASU Library Catalog.
Dissertations and Theses granted by Arizona State University are archived and made available through a joint effort of the ASU Graduate College and the ASU Libraries.

Expansive clay soils, when subjected to substantial moisture change, can be extremely problematic causing various types of damage to lightly-loaded structures. Solving these problems requires an understanding of unsaturated soil mechanics. Soil suction, related to moisture content change, is important in the development of unsaturated soil properties and in the assessment of initial and final stress for heave computation. Direct measurement of soil suction on expansive clays to determine field suction profiles is quite limited due primarily to tradition and cost-driven geotechnical field investigation practices prioritizing water content measurement over soil suction measurement. This study employs a surrogate to estimate …

A large portion of the United States is known to have problematic expansive clay soil. These expansive clay soils can cause damage to major infrastructures such as roads and lightly loaded residential buildings. The shrinking or swelling potential of unsaturated expansive clay soils requires an understanding of unsaturated soil mechanics, such as matric suction profile and the site’s environmental condition, such as climate. In unsaturated soil engineering, the most used climatic parameter is Thornthwaite Moisture Index (TMI). Since its inception, there have been several versions of TMI models in the literature. Historically, TMI is used to predict suction parameters such …
