摘　　要：按现行《混凝土结构设计规范》(GB 5 0 0 10 - 2 0 0 2 ) ,结合收集到的 95根管桩实测抗裂和极限弯矩的资料 ,经研究分析后对先张法预应力混凝土管桩抗裂弯矩和极限弯矩计算式提出修改建议 ,使计算结果能较好地符合我国管桩生产厂的实际情况 ,满足管桩生产发展的要求。According to “Design Specification of Concrete Structure”(GB 50010-2002) and actual testing data on cracking resistance and ultimate bending moment of 95 pretensioned spun concrete piles collected by the authors,two revised suggestions are offered for calculation of cracking resistance and ultimate bending moment of pretensioned spun concrete piles through research and analysis,which makes the calculation results be basically in accord with the actual conditions of spun concrete piles-producing factories in China.
