筒形基础具有造价低、结构简单等优点，作为海上风机基础有很大的应用前景。针对海上风机筒形基础所受的主要荷载，采用偏心轮和气缸实现在离心模型试验中对筒形基础所受循环荷载的模拟。在此基础上进行饱和砂土地基中海上风机筒形基础受力变形的离心模型试验，测量地基与基础的应力、变形和孔压。根据测量结果分析筒形基础的受力变形特性，表明筒形基础的临塑荷载大约是极限荷载的一半；单调和循环水平荷载作用下筒形基础发生明显的倾倒破坏，变形主要发生在筒形基础的周围。

With its low cost and simple structure,the bucket foundation has great application po-tential for the offshore wind turbine foundation.The main load of the foundation suffers horizon-tal cyclic loading,which we simulate in this study by an eccentric wheel and cylinder.We conduct centrifugal model tests on a saturated sand foundation in which we simulate and measure the stress,deformation,and pore pressure.We then analyze the deformation and stress characteris-tics of the bucket foundation according to the measurement results,which show that dumping de-struction obviously occurred under monotonic and cyclic horizontal loads,and deformation ap-peared mainly around the bucket foundation.
