风积砂风电场机组基础桩型的选择

Selection of wind turbine foundation PHC pipe-piled in electric yard in aeolian sand

介绍了某厚层风积砂丘风电场工程地形地貌及地质特点,初步分析风电机组基础地基方案的桩型选择;通过比较不同桩型特点以及性价比、应用范围、施工工艺及相关的参数来确认风积砂丘风电机组基础桩型。论证了PHC管桩在风积砂丘风电机组基础中的优势,以及施工过程中可能出现的问题与推广应用。

This paper briefly introduces topography and the geological characteristics in a wind turbine yard project in the thick aeoline sand,and preliminarily analyzes pile type selection of foundation plans of the wind turbine foundation.Through comparing the characteristic,cost performance good,application scope,construction scheme and correlative parameter of different pile types,the paper determines the pile type of the wind turbine foundation.At the same time,the paper finally presents the advantages of the prestressed concrete pipe-piled in the wind turbine foundation in the aeoline sand,the problems which may occur in the construction process and the application through the comparison.
