摘　　要：针对高桩码头整体预制装配式横梁与桩帽难以采用常规的外伸钢筋连接的问题,依托实际工程,提出一种采用型钢及梁内预留孔洞后灌浆的型钢替代法,采用数值分析方法对其结构内力及材料应力进行计算。结果表明,型钢替代法技术方案的核心在于用钢量及惯性矩的等效设计,该技术方案经验证可行。Conventional protruding bars cannot connect the integral prefabricated beam and pile cap of a high-piled wharf.In view of this problem,this paper proposes a replacement method using section steel and post-grouting of reserved holes in the beam based on an actual project.The paper uses the numerical analysis method to calculate the internal force of the structure and the stress of the material.The results show that the core of the technical scheme of the section steel replacement method lies in the equivalent design for steel content and its inertia moment.In addition,the feasibility of the technical scheme is verified.
