摘　　要：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。Based on the test and research of punching shear of one steel reinforced concrete pile cap withsix- piles and two reinforced concrete pile caps with differently arranged reinforcements and six piles, the load-bearing mechanism and analysis model of punching shear of pile caps have been investigated. It has been proved that the punching shear strength of pile cap reinforced with space steel truss can be raised actively so that the thickness of the pile cap may be decreased. Finally, some design suggestions for pile caps are put forward.
