Abstract
The liquefaction of Iron Ore Fines (IOF) during maritime transportation has got more attention in recent years. To study its liquefaction mechanism, the undrained monotonic loading tests on saturated IOF were conducted by using compression tri-axial apparatus. The static liquefaction behaviors of IOF under different densities and confining pressures were investigated. And different phenomenon has been observed on the IOF specimen. For the loose IOF specimen, slight dilate was observed and the phase transformation occurs in its stress-path curve under a high confining pressure. There is no phase transition in the intermediate density IOF sample, which shows more complex behavior. For the dense IOF specimen, a contractive behavior appears firstly then a long dilate starts. In view of these abnormal behaviors, the flow pattern failure mechanism of IOF is discussed, which provides a basis for the safe transportation of this kind of goods.
