Nanjing-Hangzhou Passenger Line Jurong River Bridge a total length of 4.155km, with three continuous beams. Due to the span of the three continuous beams, the geographical location and construction conditions vary, different methods of construction are required. Combined with the construction site, this paper introduces the construction technology and construction control points of continuous girders for railway bridges on passenger dedicated lines. From the field use situation, different construction methods play a significant role in ensuring construction safety, quality and speeding up construction progress.
