摘　　要：连续刚构桥施工期间,0#块施工质量易对后续结构施工产生影响。文章结合礼河大桥工程,根据该桥梁0#块的施工条件,梳理了设计思路,提出了具体的施工工艺。实际结果表明,该连续刚构桥的0#块托架具有可行性,施工期间无安全问题以及质量问题,结构稳定,拉杆等装置的传力路径合理,焊缝等细部的质量均可满足要求。During the construction of the continuous rigid frame bridge,the construction quality of the 0#block is easy to affect the subsequent structural construction.The article combines the Lihe Bridge project,according to the construction conditions of the 0#block of the bridge,sorts out the design ideas,and then proposes the specific construction technology.The actual results show that the 0#bracket of the continuous rigid frame bridge is feasible,there are no safety and quality problems during construction,the structure is stable,the force transmission path of the tie rods and other devices is reasonable,and the quality of the welds and other details can meet the requirements.
