摘要:
为研究非线性波浪荷载对海上风电大直径单桩累积水平位移及卸载刚度的影响 ,开展了一系列室内模型试验 , 系统分析了不同一阶谐波荷载幅值、二 阶谐波荷载幅值、循环加载频率及循环次数对大直径单桩累积水平位移和卸载刚度的作用规律 。结果表明 :一阶谐波荷载幅值、二 阶谐波荷载幅值、循环加载频率及循环次数的增加 ,均会增加大直径单桩的累积水平位移 ;随着循环次数的增加 , 卸载刚度逐渐衰减 ,一阶谐波荷载幅值的增加将加剧卸载刚度的衰减 ,而在相同循环次数下 ,二 阶谐波荷载幅值越大 ,对应的卸载刚度越大 ; 随着荷载频率的增加 ,初始卸载刚度会有所增加 ,但卸载刚度随循环次数的衰减程度也会更大 。该研究揭示了谐波效应在大直径单桩水平位移累积和卸载刚度退化中的影响 ,相关结果可为海上风电大直径单桩在非线性波浪荷载下的长期循环响应评估及设计优化提供试验依据。
