摘　　要：劲性骨架施工方法近年来在大跨径混凝土拱桥中常用,结合福建省某新建跨江大桥对劲性骨架的布置和施工进行了简要介绍,针对劲性骨架在施工阶段计算中常用的三种模拟方式进行了讨论,计算比较结果表明,梁-板组合模型的精度足够,结果可信。The stiffened framework construction method is commonly used in the long-span concrete arch bridge in recent years.According to a newly built crossing-river bridge in Fujian,the article briefly introduces the layout and construction of the stiffened framework,and discusses three simulation methods of the stiffened framework commonly used in the calculation of construction stage.The calculation and comparison results show that the beam-slab composite model is sufficiently accurate and dependable.
