This study has conducted the experimental, theoretical and numerical investigation of the transport of soil particles caused by seepage flows. The experimental results showed that the velocity of soil particles transported by the seepage flows is predictable from the equilibrium of the seepage force, exerted onto the soil particles, and the external forces. This important fact for predicting the transport of the soil particles has been verified by the theoretical and numerical analysis. The numerical analysis is expected to be applicable to the variety of phenomena, such as the seepage erosion.

本文对渗流引起的土颗粒运移进行了实验、理论和数值研究。试验结果表明，土粒在渗流作用下的运动速度可由土粒所受的渗流力与外力的平衡关系来预测。理论和数值分析都证实了这一点。数值分析可望适用于各种现象，如渗透侵蚀。
