浅谈—江西某风电场风电机基础设计及其地基处理

Discussion on Wind Turbine Foundation in Jiangxi of Electric Yard and Foundation Treatment

通过设计比较《风电机组地基基础设计规定》(试行)FD003-2007与现行《建筑地基基础设计规范》GB5007-2002,反映新编《风电机组地基基础设计规定》正确性与合理性以及风电场工程风机基础受荷不确定性和特殊性。本文通过工程实例分析了强夯法在江西某风电场风机基础位于厚层风积砂地基处理中的应用,从而使地基的压缩性降低,提高地基承载力,减少将来的地基不均匀沉降。本文同时也介绍了强夯法的特点、应用范围、施工工艺及相关的参数。

Based on constract between《Design regulations on subgrade and foundation for wind turbine generator system》(trial) FD003-2007 and《Code for design of building foundation》GB5007-2002,it reflects correctness and rationality of《Design regulations on subgrade and foundation for wind turbine generator system》and uncertainty and particularity of wind electric yard engineering wind turbine foundation load.Through examples,this paper introduce the ground treatment projects on the dynamic compaction in the Jiangxi of wind turbine yard project in the thick aeoline sand,so that the foundation of lower can also improve soil conditions for the anti-liquefaction and the uniformity of the foundation,which reduce the differential settlement may arise in the future.At the same time,The characteristic,application scope,construction scheme and correlative parameter of dynamic compaction are introduced in this paper.
