Mechanically Stabilized Earth Slope Stability (Webinar)

In Mechanically Stabilized Earth Slope Stability, you'll learn ...

• How to use geosynthetics to increase the stability of a slope
• How to perform an in-depth deep seated failure analysis using the Bishop Method of Slices
• Learn what factors contribute to slope instability and what measures to take to prevent slope failure

Overview

---

In this webinar, we will define a mechanically stabilized earth (MSE) structure and thoroughly discuss the properties of geosynthetic reinforcement strength, coefficient of direct sliding, and coefficient of interaction, as well as how these properties are used in the design of a mechanically stabilized earth structure. We will then address multiple types and strengths of reinforcement and different facing options for slopes, and when to use each facing type based on structure location and face angle.

We will also work through an example of how to analyze a slope and determine the inherent factor of safety of the unreinforced condition using the Bishop Method of Slices. Once an insufficient factor of safety is calculated, we will continue to work through the example and learn how to increase the factor of safety of a slope through the use of geosynthetics and what additional failure modes should be considered for MSE slope design. The webinar will conclude with a few short case histories of multiple failed MSE structures.

Learning Objectives

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

• Explain how various soil properties contribute to slope stability.
• Identify critical properties of geosynthetics used in slope-stability analysis.
• Describe the ramifications of an underdesigned or poorly constructed structure.
• Determine when a reinforced MSE structure is required instead of an unreinforced slope.
