Abstract In recent decades, many bulk carrier incidents, including loss of life and vessels, have occurred owing to the liquefaction of solid bulk cargoes. Currently, the transportable moisture limit (TML) is the only parameter used to determine the liquefaction potential of a mineral for maritime transport. This study aimed to investigate the influence of the particle size distribution of iron ore fines (IOF) on the liquefaction potential of bulk cargoes for maritime transport. The correlation of liquefaction potential with IOF particle size distribution is of great interest to ore transport companies, as they have a variety of IOF sizes that can be mixed to improve liquefaction potential. The effect of IOF particle size distribution on TML was investigated using the flow table test and the Proctor–Fagerberg test, and the behavior of the shear strength parameters was studied by performing a direct shear test for different IOF gradations. The samples were prepared in four different gradations, containing particle sizes from 9.5 mm to 25 μm with fines contents (

铁矿粉粒度分布对海上运输液化的影响

摘要 近几十年来，由于固体散装货物的液化，发生了许多散货船事故，包括人员伤亡和船只损失。目前，可运输水分极限 (TML) 是唯一用于确定海运矿物液化潜力的参数。本研究旨在研究铁矿石细粉 (IOF) 的粒度分布对海上运输散装货物液化潜力的影响。矿石运输公司对液化潜力与 IOF 粒度分布的相关性非常感兴趣，因为它们具有多种 IOF 尺寸，可以混合使用以提高液化潜力。使用流表测试和 Proctor-Fagerberg 测试研究了 IOF 粒度分布对 TML 的影响，并且通过对不同 IOF 等级进行直接剪切测试来研究剪切强度参数的行为。样品以四种不同的等级制备，包含从 9.5 mm 到 25 μm 的粒度和细粉含量（
