摘要:
［目的］ 随着城市轨道交通与铁路干线、城际铁路、市域铁路的互联互通、融合发展需求日益迫切，导致不同类型的轨道交通在融合贯通过程中车致振动问题不可避免，需面向多网融合运行开展综合枢纽车站振动控制研究。［方法］ 以雄安综合枢纽车站为研究对象，基于精细⁃均衡理论建立列车⁃轨道⁃车站同步耦合振动分析模型，以探究不同轨道交通模式下综合枢纽车站的振动特性及多网融合运行的叠加影响。［结果及结论］ 所建立的列车⁃轨道⁃车站同步耦合振动模型可实现多网融合运行的准确仿真；市域、城际、高速铁路引起的振动依次增大，综合枢纽车站振动与过车速度关联性强；高架层融合运行时线路临近位置振动明显增强，站台和高架候车厅振级增幅可达5 dB以上；地下层城市轨道交通引起的综合枢纽车站振动衰减快并主要影响地面候车厅，其振动与高架层高速铁路相当，二者叠加振级增幅可达2 dB。
Abstracts:
［Objective］ The growing demand for interoperation and integrated development of urban rail transit， trunk railways， intercity railways， and city railways is becoming increasingly urgent. As a result， train-induced vibration issues during multi-network integration have become inevitable， necessitating vibration control studies at integrated hub stations in the context of multi-network convergence. ［Method］ Taking the Xiong’an Integrated Hub Station as the research object， a train-track-station synchronous coupled vibration analysis model is established based on the refined-equilibrium theory. This model is used to analyze the vibration characteristics of the integrated hub station under different rail transit modes， and the superimposed effects of multi-network converged operations. ［Result Conclusion］ Research results show that the proposed train-track-station synchronous coupled vibration model can accurately simulate the multi-network convergence operation. Vibrations induced by city， intercity， and high-speed railways increase in that order， and the hub station vibration levels are strongly correlated with passing train speed. During converged operations on elevated levels， vibrations near track alignment locations significantly intensify， with platform and elevated waiting hall amplitudes exceeding 5 dB. While integrated hub station vibrations induced by underground urban rail transit attenuate rapidly， primarily affecting the ground-level waiting hall. These vibrations are comparable to those induced by elevated high-speed railway， and their superposition may increase vibration amplitude by up to 2 dB.
