By the construction of a cross-company construction and application of “Liujiaxia Suspension Bridge CFST Pylon Key Technology ” project, assessed by the expert meeting identified as the international advanced level. The main structure of the Liujiaxia Yellow River Bridge is a single-span, double-twist steel-truss stiffening girder suspension bridge with a main span of 536m and a clear net deck of 15m. The designed load rating is at the first grade and it is the strongest suspension bridge in Northwest China. Bridge project department to take and design, research institutions and other units of joint research methods, completed the steel tower micro-expansive concrete test, anchor temperature monitoring, catwalk structure design, steel deck pavement and many other research workers
