Abstract：Research purposes:As the design and construction of simply—supported steel truss girder are complex，the corresponding construction programs must be considered and the corresponding calculations and design must be made for the different construction schemesin the design process．In this paper，taking Yinghe Bridge of Luohe—Fuyang Railway as an example，the introduction is siven to the research and analysis of the design and construction of the 128 m simply —supported steel truss girder for the purpose of providing the reference to the similar design and construction works．
Research conclusions: The bridge approach of Yinghe Bridge of Luohe—Fuyang Railway is a 32 m span girder．The main bridge bias crosses the Yinghe River that is a IV class navigable fiver and it requires the bi-·direction navigation under one span．After verification of navigation and comparisons of the construction schemes，it wag decided to use 128 m simply—support steel truss girder due to the limitations of the clear height and clear width．As the construction condition was poor and the navigation could not be affected during the construction period．it needed to install the scaffold on the river bank and temporary buttress in the fiver．The girder assembly Wag conducted on the scaffold and the guide steel truss girder Was installed on the front end of the steel truss girder．The steel truss girder Wag erected with semi—cantilever dragging method，In this way，not only Was the navigation requirement met during the construction period，but also Was the construction time saved．
