摘　　要：风机基础承受风机和塔筒荷载较大,为提高可靠度,基础尺寸往往设计得较大,工程造价较高,其经济性成为人们关注的重点。桩基础和扩展基础是常用的两种基础形式,各有优劣势,前者适用范围广、造价高,后者施工简单、工期短、成本低,目前研究多集中于桩基选型方案,鲜有桩基础和扩展基础的对比研究,常按经验判断进行工程设计,缺乏数据支撑。文章结合某风电场工程,对比分析了风机桩基础与扩展基础的工程量及造价,并进一步探讨了地基土的影响,从可行性和经济性方面研究了两种基础方案,旨在为类似工程的基础选型提供参考。The wind turbine foundation bears a large load from wind turbine and tower.In order to improve the reliability,the foundation size is often designed to be large with high engineering cost.Its economy has become the focus of attention.Pile foundation and spread foundation are two commonly used foundation forms,each with its own advantages and disadvantages.The former has wide application scope and high cost,while the latter has simple construction,short construction period and low cost.At present,most of the research focuses on pile foundation scheme selection,and there are few comparative studies on pile foundation and spread foundation.Engineering design is often carried out according to empirical judgment,lacking data support.Based on a wind farm project,this paper compares and analyzes the engineering quantity and cost of wind turbine pile foundation and spread foundation,and further discusses the influence of foundation soil.Two kinds of foundation schemes are studied from the aspects of feasibility and economy,aiming to provide reference for the foundation selection of similar projects.
