Title of Presentation
Water migration in unsaturated iron ore under dynamic loads
Abstract
Dynamic loads can cause pore fluid and particle migration in porous materials, resulting in catastrophic consequences such as sinking of cargo ships at sea. This lecture focuses on experimental study of effects of load frequency, load magnitude, particle size and excess pore pressure on particle migration in unsaturated iron ore and silty sand under cyclic loads. It demonstrates that water can be “shaked” out of relatively dry samples of iron ore or silty sand, a process that resembles the mud pumping phenomenon in railway tracks. Our research busts the myth that sinking of cargo ships at sea is caused by liquefaction of the solid cargo. Rather, it is the free water that accumulated at the surface of the cargo in the cargo holder that causes the listing of the ship and destablise it.
