| 摘 要： | 在考虑地下室基础承台刚域及抗拔桩布置的情况下,对基础梁的弯矩计算进行分析推导,得出了跨中弯矩的折减系数计算公式。通过实际工程的算例分析,采用简化计算得出四桩至六桩承台不同跨度、不同桩径的折减系数,从中可以看出,考虑承台和桩的作用能够降低基础梁高度及减少配筋,做到设计上的经济合理,从而节约了工程造价。

| Abstract: | Moments on basement foundation beams considering rigid zone of pile caps and pulling resistance of piles are analyzed.Reduction factor of midspan moment is gained.A practical project is cited and a reduction factor table about various beam spans and pile diameters of 4-pile to 6-pile caps is listed to show that considering the action of pile caps can reduce beam depth and reinforcement,thereby saving construction cost. |
