Soil Mechanics: Deformation

COURSE NO: G05-003
Soil Mechanics: Deformation
Course Highlights

This online engineering PDH course, as a part of soil mechanics series, covers basic theories and practical controls of deformation 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.


Soil consists of three phases of solid, liquid and gas. In engineering, the interaction of these three phases dominates soil behavior in response to applied loads. Because of the three-phase composition, soils exhibit complex states of stress and strain (deformation). 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 (deformations).


This 5 PDH online 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 on, in, and with soils.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:


  1. Understanding typical deformation problems in approach roadway
  2. Learning about the basic theories and computations of deformations including:
  • immediate settlement
  • consolidation settlement (long-term settlement)
  • lateral movement (squeeze) of soft soils
  1. Understanding the application of soil mechanics to design in deformation control including:
  • reduction of settlement magnitude
  • reduction of settlement time
Course Document

In this professional engineering CEU course, you need to review Chapter 7, Approach Roadway Deformations of the Federal Highway Administration "Reference Manual Volume I, SOILS {C}AND FOUNDATIONS", Publication No. FHWA NHI-06-088.

Course Quiz
Once you complete your course review, you need to take a multiple-choice quiz consisting of twenty five (25) questions to earn 5 PDH credits. The quiz will be based on Chapter 7 of this FHWA Publication.


The minimum passing score is 70%. There is no time limit on the quiz, and you can take it multiple times until you pass at no additional cost.
Certificate of Completion

Upon successful completion of the quiz, print your Certificate of Completion instantly. (Note: if you are paying by check or money order, you will be able to print it after we receive your payment.) For your convenience, we will also email it to you. Please note that you can log in to your account at any time to access and print your Certificate of Completion.
