[摘要] 新建苏州火车站钢屋盖跨度大（132m），施工时间长达 3 年，南北区站房先后施工，采用累积同步滑移施工技
术从两端往中央推进，在站房中央设刚性合拢区，合拢施工技术难度大。根据工程特点以及合拢施工要求，选择合理
的施工方法，确定合拢线、合拢时间，制订有效的监测、保障措施，消除沉降、温度等不利因素影响。合拢过程结构
安全以及内力变形满足设计要求，施工技术可为类似工程提供参考。

Abstract: The span of steel roof in new Suzhou Railway Station is 132m large and the construction time is up to
three years. The station buildings were constructed successively in north and south zones. Cumulative
synchronous sliding technique was advanced from both ends toward the center and rigid closed area was
established in the central station building. Closure construction technique is rather difficult. According to the
engineering characteristics and closure construction requirements, a reasonable construction method was selected
to determine the closure line,
