锚固桩在海水养殖中应用广泛，其抗拔能力决定了海水养殖结构物的安全性能。海洋环境中的风、浪、流等循环荷载会影响锚桩的抗拔能力。通过对海水养殖锚桩进行循环加载模型试验，研究了加载幅值、初始张力角等因素对锚桩抗拔性能的影响。试验结果表明，随着荷载幅值的增大，锚桩在竖向和斜向荷载作用下的累积位移和弹性位移增大，锚桩周围土体的刚度减小。锚杆桩的稳定性降低。在加载幅值相同的情况下，随着初始加载角的增大，锚桩的横向累积位移增大。同时，竖向累积位移减小，锚桩周围土体刚度减小，稳定性降低。
The anchor pile is widely used in marine aquaculture, and its uplift resistance capacity determines the safety performance of the marine aquaculture structure. Cyclic loads such as wind, waves, and currents in the marine environment affect the uplift resistance capacity of anchor piles. By carrying out a cyclic loading model test of anchor piles for marine aquaculture, the influence of loading amplitude, initial tension angle, and other factors on the uplift resistance of anchor piles was investigated. The experimental results showed that with an increase in the loading amplitude, the cumulative displacement and elastic displacement of the anchor pile under vertical and oblique loading increase, and the stiffness of the soil around the anchor piles decreases. The stability of the anchor piles is reduced. When the loading amplitude is the same, with the increase in the initial loading angle, the lateral cumulative displacement of the anchor pile increases. Meanwhile, the vertical cumulative displacement decreases, the stiffness of the soil around the anchor pile decreases, and the stability decreases.
