在陕西湿陷性黄土区域进行风电建设，风机基础设计是风电场设计的重点和难点。本文结合在定边、靖边多风电场的建设经验，提出了风机基础适用的地基处理方法；根据风机基础的重要性、地基受水浸湿可能性的大小，通过多工程的竖向浸水试验首次提出负摩阻长度的确定方法；根据陕北地基参数特点，提出采用扩底灌注桩，充分利用桩端承载力的方法，显著减小桩长，优化风机基础工程量。为陕西湿陷性黄土区域风机基础设计提供参考。

Design of WTG foundation of the wind farm construction in collapsible loess region in Shaanxi Province is the key and difficult factor.In combination with practice of the wind farm construction in Dingbian and Jingbian countries, the foundation treatment method applicable to the WTG foundation is provided.Meanwhile, determination method of the negative friction-resistance length is proposed for the first time based on the WTG foundation importance, possibility of the foundation possibly soaked and the vertical soaking tests.Fur-thermore, the caisson pile with its end enlargement is raised according to the characteristics of the foundation parameters in northern Shaanxi Province.The bearing capacity of the pile end is fully utilized to reduce the pile length.Accordingly, the WTG foundation is op-timized in term of its volume and quantity.Those applications provide the design of WTG foundation of the wind farm construction in col-lapsible loess region in Shaanxi Province with reference.
