  • 摘要:

    The pressure distribution on hold wall of ore-slurry carrier was experimentally studied under the following conditions : (1) Ore slurry to be taken on board at slurry consistency of 60% through 75% by weight (2) Ore slurry to be subjected to the acceleration of 0. 02 g through 0. 3 g corresponding to the ship's vibration and motion. The investigation shows that (1) Ore slurry shows the behavior of homogeneous liquid during loading. (2) After loading, are gradually precipitates, and consolidates within a certain limit of acceleration of ship's motion and vibration and shows soil characteristics. (3) But so called phenomenon of liquefaction, that is, it loses shear strength and becomes in a state of liquid, is clearly observed above some acceleration limit. The conclusion reaches that the ore slurry should be treated as homogeneous liquid when calculating the pressure distribution on hold wall and examining the ship's stability.
