Sloping, Benching, Embankments and Bundwalls Course

Course Description

This course provides guidance for analyzing the static stability of slopes of earth and rock-fill dams, slopes of other types of embankments, excavated slopes, and natural slopes in soil and soft rock. Methods for analysis of slope stability are described and are illustrated by examples and case studies. Criteria are presented for strength tests, analysis conditions, and factors of safety. The methods of stability analysis discussed in this course satisfy all conditions of equilibrium

After participating in this course, you will be able to:

• Identify key issues associated with a specific slope stability problem
• Obtain parameters required for slope stability analysis of the site
• Select the method that is appropriate for the specific slope stability analysis
• Conduct preliminary slope stability analysis by design charts and/or simple calculations
• Assess results of slope stability analysis from computer software
• Recommend viable options for slope stabilization for the specific site

Course Objective

• To introduce the basic concept of  limit equilibrium in static and quasi-static slope stability analyses
• To explain common methods of slope stability analysis, computer software and design charts
• To discuss design considerations for embankments, excavations and other man-made slopes
