What might indicate that a slope is at risk of failure?

When assessing the stability of a slope, signs of cracking or shifting soil are critical indicators of potential failure. These manifestations often point to changes in the physical integrity of the slope due to factors such as water infiltration, soil erosion, or inadequate support. Cracking can signify a loss of cohesion within the soil structure, while shifting might indicate that the soil is beginning to slide or become unstable. By recognizing these signs, operators can take precautionary measures to prevent accidents and ensure safety at the worksite.

In contrast, a busy worksite or the absence of heavy machinery might not provide direct insights into the stability of the slope, and while an increasing depth of excavation can influence the slope's stability, it does not directly indicate imminent failure without accompanying signs of soil distress. Understanding these indicators allows operators to make informed decisions regarding slope management and safety protocols.
