To investigate the flow characteristics of sediments disturbed by the track of a collector vehicle during deep-sea mining, numerical simulations of continuous sediment disturbance by multiple grousers were conducted based on the Eulerian multiphase flow model. The mass and the dispersion velocity of disturbed sediments were analyzed, and the effects of in-situ disturbance, subsidence depth, and bottom-current velocity on the flow characteristics of sediments. The results indicate that when a collector vehicle travels 1.5 meters at a speed of 0.6 m/s, the mass of disturbed sediments at the water-sediment interface reaches 70.8 kg. After 2.5 seconds, the horizontal dispersion velocity of the plume reaches 0.37 m/s and the vertical dispersion velocity is 0.269 m/s. Subsidence depth increases, the dispersion intensity aggregates. In-situ disturbance causes more severe damage to the soil layer. Seabed bottom-current velocity, although being lower, can also bring influence to both the concentration and dispersion range of sediments.

为研究深海采矿时集矿车履带扰动沉积物的流动特性，基于欧拉多相流模型开展多履齿连续扰动沉积物仿真模拟，针对沉积物扰动质量和扩散速度进行分析，同时探明原位扰动、沉陷深度及底流流速对沉积物流动特性的影响。结果表明，集矿车以0.6 m/s的速度行走1.5 m的过程中，水土交界处沉积物扰动质量为70.8 kg，2.5 s时羽状流横向扩散速度达0.37 m/s，纵向扩散速度达0.269 m/s，沉陷度的增加会加大扩散的剧烈程度。原位扰动对土层破坏更严重，海洋底流速度虽小，但对沉积物扩散浓度及范围均有影响。
