摘　　要：在配有钢桁架的型钢砼六桩承台试验研究的基础上,进一步分析了这种型钢砼承台的受力性能,揭示出其传力模式就是空间桁架,探讨了它的全过程破坏机理,基于此,给出了经试验验证性能较好的承载力计算公式,然后提出了设计及应用建议。Based on the test research of steel reinforced concrete pile cap with six piles disposed by steel true, the bearing performance on this kind of steel reinforced concrete pile cap was analyzed further. It revealed that its load-transferring mode was three-dimensional strut-and-tie; the whole process of destroying mechanism is investigated in accordance with these. The bearing capacity formula that has good property through verification of test was given out; some design and applicable suggestions were put forward,
