Why Do Landslides Actually Happen? (Physical Simulation)
Have you ever wondered why solid ground suddenly collapses? In this civil engineering experiment, we use a sand model to simulate the three critical stages of a landslide.
🔬 The Science Behind the Failure:
Wetting Front Propagation: Watch how water moves through dry soil layers.
Saturation: The moment the soil becomes fully saturated, losing its "dry" stability.
Pore Water Pressure Buildup: This is the tipping point where effective stress decreases, leading to total slope failure.
Understanding these geotechnical principles is crucial for preventing disasters and building safer infrastructure.

A landslide occurs when soil becomes saturated and there is plenty of water in the soil mass to generate an excess pore water pressure. The main stages are: firstly, the soil must be saturated when lots of water infiltrates the soil mass. Then, due to the presence of water, the pore water pressure is generated, and it reduces the soil strength. When this happens, a landslide occurs.
