An anchored pile structure is a type of retaining structure that is widely used in excavation support systems, water-front structures, slope stabilization, and landslide prevention. This structure has good performance because the anchor can limit the displacement and control the deflection of the pile head. Field observations of the performance of various retaining structures during many recent earthquakes have revealed that these structures behave particularly well. However, the dynamic responses and seismic performance of this type of retaining structure in slope stabilization have not been elucidated. In this study, a large-scale shaking table test was conducted to investigate the seismic behavior of a landslide reinforced by anchored pile structures. The acceleration field, anchor force, bending moment, lateral earth pressure along the pile, and permanent displacement of the slope and pile are presented and discussed to systematically determine the seismic responses, reinforcement, and failure mechanism of this retaining structure. The tests results reveal that a landslide reinforced by anchored pile structures achieved good seismic performance even under strong earthquakes. Additionally, some reasonable measures are proposed to improve the seismic performance of a slope reinforced by anchored pile structures. The results obtained by this study can provide a theoretical basis for the seismic performance assessment and design of anchored pile structures.

锚桩结构是一种广泛用于基坑支护系统、滨水结构、边坡稳定和滑坡预防的挡土结构。这种结构由于锚杆可以限制位移和控制桩头的挠度而具有良好的性能。在最近的许多地震中对各种挡土结构性能的现场观察表明，这些结构的性能特别好。然而，这种类型的挡土结构在边坡稳定中的动力响应和抗震性能尚未阐明。在这项研究中，进行了大型振动台试验，以研究由锚桩结构加固的滑坡的抗震性能。沿桩的加速度场、锚固力、弯矩、侧向土压力，提出并讨论了边坡和桩的永久位移和永久位移，以系统地确定这种挡土结构的地震响应、加固和破坏机制。试验结果表明，用锚桩结构加固的滑坡即使在强地震下也能获得良好的抗震性能。此外，提出了一些合理的措施，以提高锚桩结构加固边坡的抗震性能。研究结果可为锚桩结构抗震性能评估和设计提供理论依据。试验结果表明，用锚桩结构加固的滑坡即使在强地震下也能获得良好的抗震性能。此外，提出了一些合理的措施，以提高锚桩结构加固边坡的抗震性能。研究结果可为锚桩结构抗震性能评估和设计提供理论依据。试验结果表明，用锚桩结构加固的滑坡即使在强地震下也能获得良好的抗震性能。此外，提出了一些合理的措施，以提高锚桩结构加固边坡的抗震性能。研究结果可为锚桩结构抗震性能评估和设计提供理论依据。
