摘要
梁板式风机基础是陆上风机基础的一种新型形式。根据室内模型试验对梁板式桩筏基础内的梁、桩、土等的受力变形特性进行深入探讨,重点讨论了竖向荷载对风机梁板式桩筏基础水平承载性能的影响。研究表明:竖向荷载可以提高梁板式桩筏基础水平承载能力;水平荷载作用下,随着竖向荷载的增加,桩顶轴力分配不均匀性减小,桩土荷载分担比减小。
Piled beam-raft foundation of wind generating set is a new form of the foundation for wind turbine on land and a indepth discussion on the mechanical and deformation characteristics of beam, piles and soil of piled beamraft foundations by laboratory model test was carried out with focus on the impact of vertical load on the lateral bearing capacity of piled beam-raft foundations. The study shows that the horizontal bearing capacity of piled beam-raft foundations will be improved under vertical load. The uneven distribution of axial pile on pilehead under horizontal load decreased with increase of vertical load and pile-soil load shear ratio reduced.
