The purposes of this paper are to describe an effective method of simulating the loading process of ore cargoes in large ore carrier, and to determine the initial stress distribution of are in a cargo hold. The experimental data on an actual ship by Hagiwara et al. are compared with the result of the present method, and they show fairly good agreement. Various loading processes and types of are hold are analyzed. From the comparison of these results, the authors come to the conclusion that the initial stress distribution of ore in an ore carrier in still water can be approximately determined by the formulation on the basis of the concept of the earth pressure at rest, which can be derived theoretically from the elastic constitutive equation for granular media proposed in the previous papers [1, 2].
