Live support chatUnreinforced Slope Stability (Webinar)
Credit: 2 PDH
Subject Matter Expert: Bill Simpson, P.E.
Type: Live Interactive Webinar
In Unreinforced Slope Stability, you'll learn ...
- How the stability of a slope changes as the properties of the soil change throughout the year and what causes these changes (time, seasonal changes, etc.)
- How various soil properties and water conditions contribute to slope stability
- Performing an analysis on a slope for the unreinforced case in both the infinite and rotational failure conditions
Overview
This webinar will address slope analysis from three different cases—cut slopes, fill slopes, and failed slopes. We will discuss factors that destabilize slopes (many of which may seem completely harmless) and how to prevent unintentionally lowering a factor of safety of an existing slope. We will also work through examples of how to analyze a slope to determine the inherent factor of safety based on the soil properties, geometry and water conditions surrounding and within the slope. The first half of the webinar will address infinite slopes and when the infinite slope condition applies. The second half of the webinar will address when a rotational slope failure should be considered and how to analyze the factor of safety by using the Bishop method.
Slope stability in both coarse and fine grained soils will be discussed, along with total and effective stress conditions. This webinar will conclude with an example of an unreinforced slope and how the inclusion of water and a tension crack influence the stability of the slope system and also look at a short case history of a catastrophic failed unreinforced slope along the side of a roadway expansion. While this webinar is for unreinforced slopes, we will mention increasing the factor of safety of a structure through the use of geosynthetics, but the details of this type of system will be discussed in a separate webinar.
Specific Knowledge or Skill Obtained
This course teaches the following specific knowledge and skills:
