摘要
富源西风电场部分风机基础天然地基岩溶发育,地基承载力不足或不均匀,经技术经济比选和论证,设计根据不同地质条件分别选用基础移位、整体和(或)局部超挖后换填毛石混凝土或砂碎石垫层、钻孔灌注桩基础等地基处理方案。文章从方案设计、施工过程管理、试验检测等方面分析评价地基处理质量,并对相关工作提出粗浅建议,以期为类似工程处理提供有益启示。
The natural foundation of some wind turbine foundation in Fuyuanxi Wind Farm has karst development,resulting in inadequate or uneven bearing capacity of the foundation.Through technical and economic comparison and demonstration,different foundation treatment schemes are designed based on different geological conditions,including foundation displacement,overall and/or partial excavation followed by backfilling with rubble concrete or sand and gravel cushion layer,and drilled pile foundation.This paper analyzes and evaluates the quality of foundation treatment from the aspects scheme design,construction process management and test and detection,and puts forward some suggestions on related work,in order to provide useful enlightenment for similar project treatment.
