Open the complete lessonSoil Liquefaction Simulation
Simulate an earthquake to observe the rise in pore water pressure and the resulting loss of effective stress in loose, saturated sand.
BuildingGround Surface
Pore Water Pressure (u)0%
Shaking causes water pressure to rise in loose sand.
Effective Stress (σ')100%
Soil strength drops as effective stress approaches zero.
