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

  • Identify key issues associated with a specific slope stability problem: Recognize and understand the critical factors affecting slope stability.
  • Obtain parameters required for site slope stability analysis: Gather necessary data and parameters for accurate slope stability assessments.
  • Select the method that is appropriate for a slope stability analysis: Choose the most suitable analysis method for evaluating slope stability.
  • Conduct slope stability analysis by simple calculations and assess software results: Perform basic calculations and interpret software analysis for slope stability.
  • Recommend viable options for site slope stabilization: Propose effective stabilization solutions for maintaining slope integrity.

This short 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. Examples and case studies describe and illustrate slope stability analysis methods. Criteria are presented for strength tests, analysis conditions, and safety factors.

Slope stabilization methods are also discussed, emphasizing the design of stable slopes and retaining structures.

Who Should Attend
Those involved with construction-related slope stability issues, analyses and design, including:
Civil Engineers • Geotechnical Engineers • Transportation Engineers • Technicians • Geologists • City & Public Works Officials/Planners
