Understanding Landslide Mechanics and Geogrid Principle

What happens here

The presenter explains the mechanics of a landslide, noting that they typically originate from a U-shaped failure zone beneath the surface, rather than just sluffing off the top. To address this, the solution involves reinforcing the soil with geogrid layers, which must extend beyond the failure zone and connect into solid, undisturbed soil. This method is similar to building engineered retaining walls.

Goal: Grasp the geological cause of landslides and the engineering solution using geogrid.
