摘 要:对比分析了10G409《预应力混凝土管桩》与03SG409《预应力混凝土管桩》和GB13476-2009《先张法预应力混凝土管桩》与GB13476-1999《先张法预应力混凝土管桩》新旧标准之间的差异;并以管桩400(95)AB桩型为例,采用新标准详细计算了混凝土管桩的有效预压应力、抗裂弯矩、抗裂剪力、桩身轴心受压承载力、桩身轴心受拉承载力。
Abstract: The standards of piles between the new and the old(10G409《prestressed concrete piles》and 03SG409《prestressed concrete piles》, GB13476-2009《Pretensioned spun concrete piles》and GB13476-1999《Pretensioned spun concrete piles》)are compared, and their differences are analyzed deeply. In addition, taking 400 (95) AB pile as an example, some mechanical calculations of concrete piles such as the effective prestressed stress, anti-cracking bending moment, anti-cracking shear, axial compression capacity and axial tensile capacity of pile body are listed in details using the new standard.
