摘　　要：采用2种防冲刷方法对单桩基础进行防护物理模型试验,研究不同防冲刷方法在某海上风电场海况下的防冲刷效果,并进行不同防冲刷方法的成本分析。结果表明,混凝土联锁排防护比抛石防护具有更佳的防护效果。混凝土联锁排防护可通过柔性变形适应土体变形,达到有效防止沙土流失的效果。经综合考虑,抛石防护搭配混凝土联锁排防护为最适合该风电场水文环境的防护方法。The physical model tests on anti-scouring of monopile foundation are carried out by two anti-scouring methods,the anti-scouring effect of different anti-scouring methods under sea conditions of an offshore wind farm is studied,and the cost analysis of different anti-scouring methods is conducted.The results show that:the concrete interlocking row protection is of stronger protection effect than riprap protection;the concrete interlocking row protection can adapt to soil deformation through flexible deformation and achieve the effect of effectively preventing sand and soil loss.Under comprehensive consideration,the riprap with concrete interlocking row protection is the most suitable protection method for the hydrological environment of this wind farm.
