An Introduction to Lateral Earth Pressure and Retaining Wall Design (Ohio Timed & Monitored Video)

In An Introduction to Lateral Earth Pressure and Retaining Wall Design , you'll learn ...

• Understanding the complete wall system and the contributing factors to the stability of the retaining wall
• Identifying forces on a retaining wall and how they work to destabilize a retaining wall system
• Realizing which properties of the soil have an effect on the design and which properties of the can be changed to increase

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 110 minutes has been met.

This course will discuss the forces that act on a retaining wall and how to properly resist those forces through the design of the retaining wall. The forces acting on the retaining wall that are to be discussed in this webinar are the earth pressure, hydrostatic pressure, and surface surcharge pressures.

These forces are all applied differently and at different locations on the back of the wall. Resistance to sliding, overturning, and bearing failures will be analyzed. The size, shape, and orientation of the wall contribute to the stability and resistance forces of the wall system.

Upon completion of this course, you will know the difference between Coulomb and Rankine earth pressure theories and be able to analyze the sliding, overturning and bearing capacity factors of safety for a retaining wall in both the dry and saturated conditions. In addition, there will be pictures and discussion from failed retaining walls due to sliding failures and over-saturation of the retaining wall backfill. This course is a great introduction to retaining wall design concepts and how the soil that surrounds them affects their stability.

This video is a recording of a live webinar training session. As a recording of a live event, you will hear the discussion that occurred between the instructor and those who attended this webinar.
