福平铁路在平潭县东海海域采用连续刚构桥跨越东北口水道,孔跨布置为(92.05+2×168+92.05)m,大桥分3幅,中间为1幅双线铁路桥,两侧各有1幅3车道高速公路桥,3幅桥孔跨布置相同,梁部和墩身分离,共用承台和桩基础,介绍该桥的设计情况。计算分析表明该桥结构刚度大,各项指标均满足规范要求,为公铁合建桥梁的设计提供了一种新的思路。
In the East China Sea, Pingtang County, the Fubin Railway crossed the northeast mouth waterway with a continuous rigid frame bridge. The hole cross was arranged as (92.05 + 2 × 168 + 92.05) m. The bridge was divided into three sections with a double-track railway bridge in the middle, Each has a 3-lane highway bridge, 3 bridge across the same layout, beam and pier separation, sharing cap and pile foundation, introduces the design of the bridge. The calculation and analysis show that the rigidity of the bridge structure is large and all the indexes meet the requirements of the code, which provides a new way of thinking for the design of the bridge for public railway construction.
