摘要:
［目的］大型综合交通枢纽结构作为城市布局的重要组成，具有投资巨大、建设规模庞大、使用功能繁杂等特点。保证此类建筑物在地震作用下免遭破坏或损伤同时保留其使用功能，以及在多重立体交通作用下使其具有足够的安全性和舒适性是具有实际意义的工程问题，因此需对相关文献研究进行整理和归纳总结。［方法］综述了各类交通荷载引起的沿线地面和建筑物等的环境振动问题，以及交通枢纽结构常采用的减隔振/震装置的研究现状；总结了现阶段国内外学者在振动响应实测、振动预测模拟和振动传播规律方面的研究成果；基于现有研究的局限性，阐述了在交通枢纽结构环境振动控制方面的未来研究方向。［结果及结论］国内外对于三维复合隔振/震的研究相对较少，研究主要集中于轨道交通沿线或上盖建筑物的地铁振动隔振，且主要集中在对所提隔振/震装置的力学性能和减隔振/震效应的试验研究。目前，对三维复合隔振/震的理论及技术研究还不够深入，三维复合隔振/震的应用还未普及并形成相关体系，相关装置的研发及其减振机理、力学性能、理论模型等仍是亟待解决的关键问题。
Abstracts:
［Objective］ Large-scale integrated transportation hub structure is a vital component in urban layout, characterized by significant investment, extensive construction scale, and diverse functionalities. Ensuring the resilience of such buildings to seismic forces, preventing damage while preserving functionality, and providing sufficient safety and comfort under the influence of complex multidimensional traffic are engineering challenges of practical significance. Thus, it is necessary to sort through and summarize relevant literature research on this subject. ［Method］ The environmental vibration issues caused by various traffic loads along routes and buildings are reviewed. Additionally, the research status of vibration/seismic isolation devices commonly used in transportation hub structures is explored. The research achievements of scholars in China and worldwide in vibration response measurement, vibration prediction simulation, and vibration propagation laws are summarized. Based on the limitations of existing researches, the future research directions in environmental vibration control for transportation hub structure s are discussed. ［Result & Conclusion］ There is relatively limited research on three-dimensional composite vibration/seismic isolation globally, with a main focus on metro vibration isolation along rail transit lines or superstructures. Research primarily concentrates on experimental studies of the mechanical performance of the proposed vibration/seismic isolation device and vibration/seismic isolation effects. Currently, theoretical and technical research on three-dimensional composite vibration/seismic isolation is not deep enough, and its application is not yet widely adopted or developed into a system approach. Key issues, such as the development of related devices, vibration reduction mechanisms, mechanical performance, theoretical models, remain crucial problems that urgently need resolution.
