中文摘要：
针对海上风电场单桩基础结构的冲刷问题进行物理模型试验研究，采用7个直径分别为0．025、0．050、0．075、0．100、0．400、0．700、1．000m的模型，试验流速根据实验室条件分别取0．1、0．3、0．5和0．6m／s。试验结果显示，桩的冲刷深度与桩径的关系呈二次抛物线型。冲刷深度与桩径的比值随桩径的增大呈二次抛物线衰减，无量纲冲刷深度随流速的增大也呈二次抛物线增大，与DNV规范的推荐计算方法吻合。冲刷坑的大小与冲刷深度的比值基本为常数，与现行规范的计算方法吻合。
英文摘要：
The experimental investigation for the scour of monopile foundation structure of offshore wind turbine was carried out. 7 models with 0.025 m, 0.050 m, 0.075 m, 0.100 m, 0.400 m, 0.700 m and 1.000 m diameters were designed and 4 levels of flow speed ranged from O. 1 m/s to 0.6 m/s were tested to investigate the effects of pile diameter and flow speed on the local scour depth and the lateral extension of the scour hole around pile. The results show that the scour depth is nonlinearly increased with the pile diameter. It shows a curve of quadratic parabola. The ratio of the scour depth and pile diameter nonlinearly decreases with the pile diameter increasing and increases with flow speed. It coincides with the calculation method recommended in the DNV standard. Also, the ratio of the lateral extension and depth of the scour hole is basically a constant as that in the standard.
