In order to attain the soil movement and explore the penetration mechanism of open-ended pipe piles in saturated sand, the transparent granule, which could substitute the natural sand, was used to simulate the pile jacking with different pile sections. The granule displacement vector field, the plug neutral surface and the plug height were obtained. Test results showed that when the pile inner radius is larger, the squeezing displacement and the plug height are larger. Normalization of the horizontal and vertical components of granule movement employing the pile outer radius showed that the 4d range of the pile end was the area where the inner shaft resistance exerted. In addition, it was found that the linear relationship between incremental filling ratio (IFR) and plug length ratio (PLR).
