Course: Slope Stability: Analysing Factor of Safety and Probability of Failure

Course Outline:

Slope stability models rely on a comprehensive understanding of material strengths, geological features, structural conditions, and hydrogeological influences. These models often involve significant natural variability and inherent uncertainty in their input parameters, which can impact the reliability of design outcomes.

Join us for a two-day workshop which will empower you to:

• Understand how variability in material properties and groundwater conditions impacts slope stability models.
• Learn methods to incorporate uncertainty into your analysis to improve reliability.

Through hands-on practical examples, participants will learn the key differences between the traditional Factor of Safety approach and the more rigorous Probability of Failure analysis, using Slide2, RS2 and RocFall2.

Designed for engineering geologists and geotechnical engineers, this workshop offers an opportunity to deepen your understanding of risk-based design and modern analytical approaches. By the end of the course, you’ll be equipped with the knowledge and skills to confidently apply advanced slope stability techniques to your projects.
