| Abstract: | The railway corridor in central and southern Shanxi pass over Beijing-Shanghai-Railway,and the super-large bridge adopts 96 m steel truss spanning Beijing-Shanghai-Railway.The steel girder is overall assembled,and is dragged in position with no guide beam at the front end but with additional temporary buttress between the two main piers.Taking this bridge as an example,the erection of steel truss girder passing over an existing railway is explored. |
