Due to process limitation, the laying accuracy of the traditional subway track bed is low, and the construction speed is slow, while the construction accuracy and efficiency of the prefabricated track bed are relatively high. In addition, many subway lines often require the addition of vibration reduction measures or an upgrade in the vibration reduction levels after a period of operation. Therefore, it is urgent to develop the prefabricated damping pad floating slab track (PDPFST) with various vibration reduction grades and convenient upgrade options for vibration reduction. Therefore, the PDPFST was developed and applied to three new metro lines in Qingdao. In this paper, the coupled simulation analysis and field tests were conducted on the dynamic performance and vibration reduction performance of the vehicle passing through the PDPFST. Firstly, the structure and construction technology of the PDPFST were introduced. Then, the requirements and evaluation methods for the simulation and test of dynamic performance analysis and vibration reduction effect analysis were presented. Then, a vehicle-floating slab track-tunnel coupled dynamic analysis model was established. Finally, the coupled simulation results were compared with the field test results. Through the above research, the following conclusions are drawn: Compared to the traditional track slabs, the construction progress of the PDPFST is increased by 3 times (approximately 110 meters per day). The simulation results of the dynamic performance and vibration reduction performance of the vehicle passing through the PDPFST are in good agreement with the measured values, and the dynamic performance of the vehicle meets the requirements. When the vibration frequency is greater than
times the natural frequency, the floating slab track can exhibit a good vibration reduction effect. The vibration reduction effect of the PDPFST is remarkable. The high vibration reduction effect is approximately 13 dB and the medium vibration reduction effect is approximately 8 dB. The research results can provide a certain theoretical and practical reference for the design and implementation of the PDPFST.

传统地铁道床作业受工艺限制,铺设精度较低,现场施工进度缓慢,而预制装配式道床施工精度和效率都相对较高。此外,许多地铁线路运营一段时间后往往面临着增设减振措施或升级减振等级的需求。因此,亟待发展减振等级多样且减振等级升级方便的预制式减振垫浮置道床技术(prefabricated damping pad floating slab track,PDPFST)。基于此,研发了PDPFST技术,并将此技术先后运用到青岛3条新建地铁项目。文中对车辆通过PDPFST的动力学性能和减振性能进行了耦合仿真分析以及现场试验研究。首先,对PDPFST的结构和施工工艺进行了介绍。然后,介绍了动力学性能分析和减振效果分析的仿真及测试的要求和评判方法。接着搭建了车辆-浮置板-隧道耦合动力学分析模型。最后,将耦合仿真结果和现场实测结果进行了对比分析。研究结果表明:相比传统的轨道板,PDPFST施工进度提高了3倍(约110 m/d);车辆通过PDPFST的动力学性能、减振性能仿真值和实测值吻合较好,且车辆的各项动力学性能均能满足标准要求;当振动频率大于
倍固有频率时,浮置板系统能够起到较好的减振效果;PDPFST的减振效果显著,高等减振约为13 dB,中等减振约为8 dB。研究结果可为后续的PDPFST的设计和实施提供了一定的理论和实践参考。
