The pre-stressed reinforced concrete box girder has been one of the most common structures on the railways,highways and urban roads in recent years,and the quality of construction directly affects the overall structure. Based on the construction practice of the pre-stressed reinforced concrete box girder of an overpass, the key construction technologies of the pre-stressed reinforced concrete box girder are discussed,the specific measures of key construction process and technical reference for the construction of pre-stressed reinforced concrete box girder are put forward.
