In recent years, with the fast development of high-speed railway in China, more and more bridges appear in the railway. At present, the problem bearing plate hollowing of box beam is a hidden trouble generally existed in the construction of the body of the railway bridge. In line with the construction of cast-in-situ simply supported beam and continuous beam of viaduct in Guangning station of GuiGuang railway, construction technology and measures of how to avoid hollowing of bearing plate of box beam is mainlv introduced,providing references and examples for the safety of bridge construction.
