Geotechnical Engineering Series - Earth Retaining Structures (Ohio Timed & Monitored)

In Geotechnical Engineering Series - Earth Retaining Structures, you'll learn ...

• Classification of earth retaining structures based on load support mechanism, construction method and system rigidity
• Effects of cohesion, wall friction and wall adhesion on lateral earth pressure
• The impact of surcharge loads on retaining walls
• How to check retaining walls for the four basic modes of instability

Overview

To meet the Ohio Board's intent that online courses be "paced" by the provider, a timer will be used to record your study time. You will be unable to access the quiz until the required study time of 200 minutes has been met.

This course, as a part of the Geotechnical Engineering Series, covers basic theories, engineering evaluations, design approaches, and practical CQC (construction quality control) procedures for the design and construction of retaining walls. Although the focus of the course is on earth retaining structures for surface transportation facilities, much of the material is applicable to other applications.

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 earth retaining structures.

Learning Objectives

Upon completion of this course, participants will be able to:

• Explain the general approach to retaining structure design.
• Distinguish among the types of earth retaining structures.
• Identify considerations for selecting a retaining structure.
• Describe lateral earth pressures acting on retaining structures.
• Identify how cohesion affects lateral earth pressures.
• Explain the effects of wall friction and wall adhesion on lateral earth pressures.
• Identify lateral pressure caused by water.
• Explain lateral pressure resulting from surcharge loads.
• Apply the design steps for retaining walls, including checks for bearing capacity, overturning, sliding, global stability, settlement, and tilt.
• Describe drainage systems used for retaining structures.
• Explain construction monitoring and inspection practices for retaining structures.

Certificate of Completion

You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 30 questions. PDH credits are not awarded until the course is completed and quiz is passed.
