摘　　要：文章针对内河航道桥梁施工技术的特殊要求,以昆仑桥工程为实例,提出了一套切实可行的施工技术方案。首先分析了内河航道桥梁施工的特点,包括施工场地狭小、船舶交通频繁等限制因素。而后详细探讨了昆仑桥工程的概况和主要技术难点,包括钢桥线性控制和钢梁拱吊装施工等方面。在此基础上,提出了解决难点的具体措施和施工关键技术,如大节段整体吊装、横梁片拼装精度控制措施等。通过对昆仑桥的实例研究,文章提出的施工方案可为类似工程提供借鉴。This paper proposes a practical and feasible construction technology plan for the Kunlun Bridge project,taking into account the special requirements of construction technology for inland waterway bridges.The paper first analyzes the characteristics of bridge construction in inland waterways,including limited factors such as narrow construction sites and frequent ship traffic.Afterwards,a detailed discussion was conducted on the overview and main technical difficulties of the Kunlun Bridge project,including linear control of steel bridges and lifting construction of steel beam arches.On this basis,specific measures and key construction technologies were proposed to solve the difficulties,such as overall lifting of large sections and precision control measures for beam assembly.Through the case study of Kunlun Bridge,the construction plan proposed in this article can provide reference for similar projects.
