【Objective】 Sealing breaches in river levees is difficult to accomplish quickly. Utilizing rocket anchor penetration technology to rapidly establish anchoring points at a breach can effectively improve the anti-scour stability of cast materials. To provide an effective solution for rapid levee breach closure, this study investigates the penetration process and mechanical characteristics of rocket anchors in different media. 【Methods】 A single rocket anchor was selected as the research object, with soil chosen as the penetration medium. A three-dimensional numerical simulation was conducted to establish a mathematical model of rocket anchor penetration. Simulations were conducted under various initial conditions. The three-dimensional simulation of penetration into soil was used to investigate, at a microscopic level, the stress state of the anchor, the plastic strain of the soil, and the morphological characteristics of the cavity formed by the anchor penetration. 【Results】 The simulation results showed that the localized pressure field caused by soil resistance was mainly concentrated at the anchor head, with the pressure gradient exhibiting unstable variation. During penetration, changes in the Von Mises equivalent stress of the soil at the anchor boundary responded synchronously with changes in the pressure field, and their fluctuation patterns were basically consistent. The initial velocity of the anchor affected its penetration depth in the soil. As the initial velocity increased, the penetration depth increased, but the stability of the anchor decreased. When the initial velocity exceeded a critical value, the anchor deviated, resulting in reduced penetration depth. 【Conclusion】 The findings contribute to the design of rocket anchors for emergency rescue and provide a theoretical basis and technical support for the application of scientific and efficient breach closure technologies.
