Slopes are integral components of both natural landscapes and human-made constructions. However, slope stability can be compromised, leading to slope movements or landslides that pose significant risks to infrastructure and human lives. In this blog post, we will delve into the world of slope stability, exploring the causes of slope failures, different types of landslide movements, and the methods employed to assess and mitigate slope instability. Causes of Slope Failures: Slope failures can be attributed to various natural and human-induced factors. Natural causes include gravitational forces, water saturation, erosion, seismic activity, changes in aquifer levels, volcanic eruptions, and freeze-thaw weathering cycles. On the other hand, human-induced causes encompass activities such as toe excavations, infrastructure loads, machine vibrations, construction of weak embankments or earth dams, and deforestation, which can exacerbate slope instability. Types of Landslide Movements: Lands...
