本文通过对1块型钢混凝土六桩承台、2块不同布筋形式的钢筋混凝土六桩承台受冲切的试验研究,探讨了桩基厚承台的受力机理和分析模式,证明了在桩基厚承台内按空间桁架形式配置型钢可有效地提高承台的抗冲切承载力,从而降低板厚。并提出了桩基承台和筏板的设计建议。 In this paper, through a test study on a six-piece cap of steel reinforced concrete and two six-piece caps of reinforced concrete in different forms, the mechanism and analysis model of the bearing capacity of the pile cap were discussed. The configuration of steel sections in the form of space truss in thick pile foundations of pile foundations can effectively improve the punching shear bearing capacity of the pile caps, thus reducing the plate thickness. And put forward the design recommendations for pile foundation slabs and rafts.
