由于白面石武水大桥是铁道部的科研项目,试验工程,是铁四院第一次设计,铁隧局第一次施工的铁路桥梁建设史上的第一座悬臂灌筑的铁路预应力钢筋混凝土连续梁双线桥,跨度大,预应力吨位大,为了保证该梁施工万无一失,因此,在梁下先浇筑了试验梁段,进行了工艺试验,现就预应力体系 As the Mianbai Shibuya Mizuho Bridge is a research project of the Ministry of Railways, pilot project, is the first design of the Fourth House of Iron and Steel, the first construction of the railway tunnel construction history of the first railway bridge cantilevered steel prestressed concrete Continuous beam double-line bridge, large span, large prestressed tonnage, in order to ensure the construction of the beam foolproof, therefore, in the beam first pouring the test beam section, the process test, is on the prestressed system
