【Objective】 To meet the requirements of rapid and efficient emergency response to dike breaches, this study investigates the penetration motion characteristics of a cabled dynamic anchor across different media. 【Methods】 A transparent Slime gel was adopted as the test medium, and a visualized penetration experimental apparatus was designed and developed. Using a generalized dynamic anchor as the research object, penetration experiments of the cabled dynamic anchor were conducted under different initial conditions. Through multiple sets of experiments, measured data, including penetration trajectory, velocity, interface oscillation, and anchoring force, were obtained. 【Results】 The penetration trajectory of the anchor approximately followed a cubic function pattern, and the anchor exhibited a significant deflection toward the inner side of the interface normal before coming to rest. After entering the gel, the anchor velocity decayed rapidly, and the initial launch conditions had a significant influence on the penetration characteristics of the anchor. The penetration depth exhibited an approximately logarithmic response relationship with the launch force, while a strong positive correlation was observed between the penetration depth and the anchoring force, which followed an exponential functional trend. 【Conclusion】 The functional relationships for anchor velocity decay and trajectory change are approximately similar. Furthermore, the anchor deflection is greatly influenced by the launch angle. In addition to affecting the penetration depth, the initial launch conditions of the anchor also directly influence its anchoring force. These findings contribute to the advancement of theoretical research on cross-media penetration and to the design and development of dynamic anchors for emergency rescue applications.
