摘要:
以福州滨海软土区某地铁场站及其上盖结构为工程依托,通过现场测试与数值模拟分析了咽喉区列车振动波在上盖五层结构内的传播规律。研究表明:上盖结构房间楼板振动沿楼层向上呈现先衰减后放大的趋势,且各层振动卓越频带为40~80 Hz,其中首层峰值频率为63 Hz,三层与五层均为50 Hz;各层房间柱振动均大于楼梯间柱,且房间柱振动沿楼层向上呈现先衰减后放大的趋势,楼梯间柱振动在各楼层内则基本保持不变;首层与五层房间楼板竖向分频最大振级VLzmax 分别超限15.2dB 与3.2 dB,各层房间柱与楼梯间柱VLzmax均未超限;柱截面尺寸增大至0.5 m×0.5 m 时,上部楼层房间楼板VLzmax可降低2.2~5.1 dB,楼板厚度增大至0.2 m 时,下部楼层VLzmax可降低1.4~2 dB。本研究成果可为地铁场站及其上盖结构列车致振响应研究与优化设计提供理论借鉴。
Abstract:
Based on a subway station and its superstructure in the coastal soft soil area of Fuzhou, the propagation of train vibration waves in the five-story superstructure in the throat area was analyzed through field tests and numerical simulations. The study shows that: the vibration of the floor slab of the superstructure room shows the trend of attenuation and then amplification along the floor, and the vibration excellence frequency band of each floor is 40 Hz~80 Hz, in which the peak frequency of the first floor is 63 Hz, and that of the third and fifth floors is both 50 Hz; the vibration of the room columns of each floor is greater than that of the stairwell columns, and the vibration of the room columns shows the trend of attenuation and then amplification along the floor, and the vibration of the stairwell columns is basically unchanged in all the floors; VLzmax of vertical crossover frequency of the floor slab of the first floor and the fifth floor exceeds the limit by 15.2 dB and 3.2 dB, respectively, and the VLzmax of the room column and the stairwell column of each floor does not exceed the limit; VLzmax of the upper floors can be reduced by 2.2 dB~5.1 dB when the column cross-sectional size is increased to 0.5 m×0.5 m, and VLzmax can be reduced by 1.4 dB~2 dB when the floor thickness is increased to 0.2 m. Results of this research can provide theoretical reference for the research and optimal design of train vibration response of subway stations and their superstructures.
