摘　　要：为研究无缝钢轨位移变化情况,采用光学钢轨纵向位移监测设备和磁式钢轨纵向位移监测设备,对京沪高铁济南铁路局管内正线(K316+255)~(K691+895)无缝线路、正线道岔51组及黄河特大桥4组单向调节器在2012—2014年的位移变化情况进行观测,分析并给出了京沪高铁无缝线路、正线道岔及黄河特大桥调节器钢轨位移变化规律。In order to study the change of the seamless rail displacement,the displacement changes of the K316+255 to K691+895 seamless line,the straight line turnout 51 groups and the 4 sets of unidirectional regulators of the Yellow River super large bridge in the Ji’nan railway of Beijing-Shanghai high-speed railway in 2012 to 2014 are adopted in the longitudinal displacement monitoring equipment of the optical rail and the magnetic rail longitudinal displacement monitoring equipment. According to the observation and analysis,the variation rules of rail displacement of BeijingShanghai high-speed railway,seamless rail,main line switch and the Yellow River super large bridge regulator are put forward.
