In the context of earthworks, what does "slope stability" mean?

Slope stability refers to the ability of a slope to maintain its position without collapsing or sliding. This concept is crucial in earthworks, as it determines the safety and sustainability of embankments, cut slopes, and other structures that exist on or near inclined surfaces.

When assessing slope stability, various factors such as soil type, moisture content, the angle of the slope, and external loads are considered to evaluate the risk of slope failure. Understanding these factors is essential for engineers and surveyors to design safe structures and implement necessary measures to mitigate potential landslides or erosion. Proper analysis of slope stability ensures that earthmoving activities are conducted without compromising the land's integrity and that water drainage is managed effectively, further preserving the stability of the slopes.
