Overview
Soil consists of three phases of solid, liquid and gas. In engineering, the interaction of these phases dominates soil behavior in response to applied loads. Because of the three-phase composition, soils exhibit complex states of stresses and strains. A key task in the design and construction of facilities on, in, and with soils is proper quantification of these states of stress, and their corresponding strains.
This course, as a part of the soil mechanics series, covers basic theories and practical applications of stress and strain in soils. Human beings have been building structures on, in, and with soils for centuries, and the principles of soil mechanics have been used for a long time, whether they were theorized or not.
This course is applicable to geotechnical, civil, mining, structural, and environmental engineers, as well as design and construction personnel involved with the planning, design, and construction of building structures that utilize soils.
In this course, you need to review Chapter 2 – Stress and Strain in Soils from “Reference Manual Volume I, SOILS AND FOUNDATIONS”, Publication No. FHWA NHI-06-088, by Federal Highway Administration of U.S. Department of Transportation.
To earn PDH credits, you must pass a multiple choice quiz consisting of twenty-five (25) questions.
