Abstract：Research purpose: Adjustment on distance between lines and length of transition curve brings several bridge rehabilitation projects, during the construction of the sixth speed-increasing on railway line. By means of moving beams of bridge, functions of existing bridge can be exerted at full capacity, while the duration of improvement construction can be shortened significantly.
Research method: The paper gives a detailed introduction on construction technique of 3-20 meters long simple-supported T-type beam integral moving on the sixth speed- increasing on railway line of Jin-pu line. Aiming at the character of anchor submerged in the bridge steel bearings to fix lower pendulars, according to circumstances of the site, several construction methods are skillfully used to complete the task of high tonnage bridge beam lateral moving without influencing normal operation of train, such as using steel plate to fix the existing steel bearings, combining vertical jack with lateral jack, utilizing "window time" of track operation at night, using technique of lining of track.
Research result: it helps to meet the requirement of the speed of 200 km/h.
Research conclusion: Through the observation following beam moving, beam can maintain stability in structure and reliability in quality which reaches the expected effect. Practice has proved that this beam moving technique can be applied successfully and feasibsly.
