摘要:
［目的］预制钢筋混凝土构件的连接方式对装配式地铁的安装便捷性和结构稳定性至关重要。然而，目前相关研究多为局部分析，缺乏对连接方式的系统性综述与比较。因此，有必要对装配式地铁预制构件连接方式的研究现状和技术进展进行全面总结，为技术选择与优化设计提供科学依据。［方法］系统梳理了现浇连接、钢筋灌浆套筒连接、螺栓连接、焊接连接及钢构件快速连接等5种主流连接方式在国内外的研究进展。结合具体工程案例，深入分析了这些连接方式的优缺点及其适用场景。［结果及结论］现浇连接和钢筋灌浆套筒连接作为湿连接方式，展现出较高的承载能力和可靠性，但它们的施工周期较长，工艺相对复杂，特别是现浇连接易受施工环境限制，影响效率；钢筋灌浆套筒连接虽减少了浇注工作量，但对技术要求严苛且成本较高。螺栓连接、焊接连接与钢件快速连接作为干连接方式，无需湿作业，施工相对简便。然而，螺栓连接工序繁琐，承载能力有限；焊接连接对工艺水平要求较高，且对工况敏感；而钢件快速连接则以其施工快捷、质量可靠及承载能力强的综合优势，在复杂工况和空间受限环境中尤为适用。
Abstracts:
［Objective］ The connection methods of prefabricated concrete components are crucial for the installation efficiency and structural stability of assembled metro systems. However, current research predominantly focuses on localized analyses, lacking a systematic review and comparison of these connection methods. Therefore, it is essential to comprehensively summarize the current research status and technological advancements in connection methods for prefabricated metro components, providing a scientific basis for technological selection and design optimization. ［Method］ The research progress in China and abroad is systematically sorted, focusing on five mainstream connection methods: cast-in-place connection, steel grouting sleeve connection, bolted connection, welded connection, and steel component quick connection. Specific engineering cases are examined to analyze the strengths, weaknesses, and applicable scenarios of each connection method. ［Result & Conclusion］ Cast-in-place and steel grouting sleeve connections, as a wet connection method, exhibits high load-bearing capacity and reliability. However, these methods involve longer construction cycles and relatively complex processes. Cast-in-place connection is particularly sensitive to construction environment constraints, affecting efficiency. Although steel grouting sleeve connection reduces the amount of casting work, it is technically demanding and has higher costs. Bolted connections, welded connections, and steel component quick connection, as dry connection methods, eliminate the need for wet operations and offer relatively simpler construction. Bolted connection, however, is labor-intensive and has limited load-bearing capacity; welded connection requires high technical proficiency and is sensitive to working conditions. Steel component quick connection, with its advantages of fast construction, reliable quality, and strong load-bearing capacity, is particularly suitable for complex working conditions and space-constrained environments.
