摘　　要：基于钢混叠合梁墩顶梁段架设工艺受环境及资源配置影响较大,需根据现场实际情况选择合理的架设工艺。以珠海洪鹤大桥磨刀门水道主航道桥项目为例,对主塔区墩顶梁段架设工艺进行探讨研究,提出了传统的支架法、创新型无支架法两种架设工艺。分析总结两种施工工艺的优缺点,根据桥位现场实际情况,2个主墩选用了不同的架设工艺进行墩顶梁段施工,均在项目实施中取得良好效果,可为后续同类桥梁施工提供借鉴。The erection process of the top beam section of the steel concrete composite beam pier is greatly affected by the environment and resource allocation, it is necessary to choose a reasonable erection process according to the actual situation on site. Taking Zhuhai Honghe Bridge Modaomen Waterway main channel bridge project as an example, the erection process of the pier top beam section of the main tower area was discussed and researched, two kinds of erection processes, traditional erection method and innovative erection method, were proposed. The advantages and disadvantages of the two construction processes were analyzed and summarized. According to the actual situation of the bridge site, different erection processes were selected for the two main piers to the construction of the top beam section of the pier, both have achieved good results in the project implementation, provide reference for subsequent similar bridge construction.
