The structures in the riverbed or seabed may be affected or damaged by emergency anchoring. In the channel with frequent navigation, the emergency anchoring penetration depth need to be fully considered during the design of the buried depth of structures in riverbed. In this paper, small scale model tests are carried out to simulate the process of anchoring penetration of hall anchor in silty sand, and the influences of different impact velocities (1.15−4.4 m/s) and relative density of silty sand (0.45−0.65) on anchoring penetration depth are investigated. Based on the Terzaghi ultimate bearing capacity theory and the energy conservation law, the expression of penetration depth of the hall anchor in silty sand is deduced, and the theoretical calculation results are conservative compared with experimental results, the revised results of the theoretical calculation results are in good agreement with experimental data. The research results can provide a reference for the design of buried depth of structures in silty sand riverbed or seabed.
