桥梁加固或拓宽通常采用半幅施工、半幅行车模式施工，新浇筑混凝土不可避免会遭受车桥耦合振动影响，导致其力学性能和耐久性降低。本文归纳整理了国内外各类桥梁的振动参数和实验室模拟方法，分析了车桥耦合振动对混凝土离析程度、力学性能、界面粘结与裂缝萌生的影响，探讨了车桥耦合振动导致组分迁移、孔结构劣化和界面损伤的破坏机理。在此基础上，总结了车桥耦合振动下缩短混凝土受扰时间、增强其韧性和提高自愈能力等调控措施。为车桥耦合振动条件下混凝土性能调控提供理论依据，对桥面维修加固中混凝土设计、制备与养护具有重要参考价值。

Mastering the impact of vehicle-bridge coupling vibration on the mechanical properties and durability of early-age concrete is crucial for implementing effective countermeasures based on the extent of damage. This vibration typically occurs during bridge widening and reinforcement projects, particularly when employing a half-width construction and half-width traffic. This review summarizes recent advancements on the concrete performance changes and modulation under vibration environments induced by vehicles or trains, focusing on the characteristics of vehicle-bridge coupling vibration, the evolution of concrete properties, its underlying mechanisms, and the existing modulation measures. The aim is to thoroughly analyze the impact of vehicle-bridge coupling vibration on the concrete performance and explore the corresponding modulation strategies, thus providing theoretical guidance and design references for such construction methods.

The spatial variation in bridge vibration response is affected by a combination of factors, including structural modal characteristics, vehicle speed and load position, as well as boundary conditions. The vibration of a bridge is closely related to its structural design, and the stiffness and the natural frequency decrease as the span increases, leading to larger vibration amplitudes. Vibrations exhibit a significant spatial non-uniformity, with the dominant vertical response and the most pronounced vibration at mid-span. An increase in vehicle speed and load enhances the impact effect, potentially exciting higher modes and even causing resonance, further amplifying the vibration amplitude. The expansion joints at the ends of the bridge and the junctions between new and old bridge sections, due to differences in connection status or structural discontinuity, are prone to local disturbances or resonance phenomena, intensifying the vibration response.

Vehicle-bridge coupling vibration significantly affects the structure and performance of concrete, and the interaction between these factors is closely related. Vibration leads to the migration of material components, reducing the yield stress of the cement paste, which in turn causes segregation and affects the stability of mechanical properties. Moderate vibration refines the pore structure, enhancing density and improving concrete performance, while high-intensity vibration coarsens the pores, induces cracks, and reduces overall performance. Moderate vibration can also damage the semi-permeable membrane layer on the cement surface, promoting cement hydration, generating more C-S-H gel, and improving the performance. However, excessive vibration or vibration during sensitive periods can disrupt the gel interconnections, weakening concrete performance. High-intensity and sensitive-period vibrations further damage the interfacial transition zone, increase porosity, and induce microcracks, thus leading to a significant performance degradation.

Modulation measures for vehicle-bridge coupling vibration mainly include reducing the disturbance time, enhancing material toughness, and improving self-healing ability. Reducing disturbance time can be achieved by using early-strength agents/cement or composite admixtures/cement, enabling concrete to gain strength quickly and resist the adverse effects of vibration. Enhancing material toughness can be achieved via incorporating steel fibers, synthetic fibers, basalt fibers, or other materials, improving the stress transfer and crack modulation ability of concrete. Improving self-healing ability involves activating hydration reactions or releasing repair substances during the early stages of crack formation to seal microcracks, restoring material structural integrity and improving service stability. Moreover, reducing disturbance time and enhancing material toughness are applied in engineering with the significant results.

Summary and prospects

This review summarizes the latest research progress on the performance changes and modulation of early-age concrete under vehicle-bridge coupled vibration, focusing on the analysis of vibration characteristics, concrete performance changes, and the underlying mechanisms, and discussing the existing modulation measures. Future research should develop lab-scale simulation methods that more closely reflect actual vibration characteristics, considering the coupling effects of temperature, humidity, load, and corrosion, to comprehensively explore the evolution of concrete performance under practical conditions. In addition, in-situ characterization systems for vibration loading should be also developed, using techniques such as 3D CT, NMR, DIC, and acoustic emission to capture the evolution of the concrete microstructure and crack dynamics, thus providing a basis for the design and life prediction of vibration-resistant concrete.
