摘　　要：本文依托广佛环线32.6m跨径连续箱梁施工为例,详细介绍了一种上行式移动模架在过门型墩时的一种施工方法,该方法采用直接提升挂梁的形式,将挂梁提升至非干涉部位后按常规施工流程过跨。此方法相比较于调整支腿的方法较为安全,直接,经济,可循环。能够完美解决上行式移动模架在施工中遇到门型墩柱时由于模架开模宽度有限挂梁底部不能完全避开墩身的技术难题。Based on the construction of the 32.6m span continuous box girder of Guangfo loop line, this paper introduces a kind of construction method of upstroke moving carrier crossing door type pier. By this method, the suspended beam is directly lifted to the noninterference part and then crossed according to the conventional construction process. Compared with leg adjusting method, this method is relatively safe, direct, economic and recycled, and can perfectly solve the technical problems in the construction of upstroke moving carrier crossing door type pier.
