摘　　要：采用移动模架施工多跨连续梁时,线形控制有其自身的特点。分析了采用这种施工技术时,影响梁体线形的诸多因素,并结合苏通长江大桥北引桥的施工实践,说明梁体线形控制的方法及意义,最后总结了采用这种施工方法时梁体线形控制需要注意的关键点。The geometrical alignment control for the construction of multi-span continuous girder bridges with MSS （ Movable Support System） has its own characteristics. In this paper, various influence factors for alignment control are analyzed using MSS technique. Combined with the problems occurred in the north approach of Sutong Yangtze River Bridge, the importance and methods of alignment control are expounded. In the end, some key measures for alignment control are summarized.
