Chapter Overview
• Chapter 2 introduced you to the basic slopes stability. Students need to know the soil’s behaviour when the sliding occurs.
• Awareness of the shearing resistance is important in order to analyze soil stability problems.
Learning Objectives
• To introduce the basic concept of slope stability. • Students manage to know the soil condition
when slope started to fail. • Student can understand the causes that make
the slope fail. • They also can take precaution method when
designing the slope stability to avoid slope failure.

Learning Outcomes
• On completion of this topic, students must be able to understand the characteristics of the soil when it’s started to slide.
• Able to describe the causes that make the slope fail.
• Able to explain certain method to avoid slope failure.
