摘要

    摘要
  • 摘要: 以北京地铁某线区间盾构隧道为背景, 结合现场调查和初步实测, 识别出盾构施工诱发振动的主要振源为刀盘与地层相互作用、渣土/管片运输车辆、盾构内部设备引起的振动.通过现场实测与数值模拟分别对振源的特性展开研究, 结果表明:刀盘掘进诱发振动频带较宽, 主频主要集中于20~90 Hz;后配套车信号振动幅值较小, 幅值较大的频带带宽为0~20 Hz;运输车由于临时轨道均直接与隧道结构接触并相互作用, 使得中高频未得到衰减, 幅值较大频率主要集中于70~90 Hz, 振动传至地表后主频衰减至20 Hz以下, 振动影响范围主要为隧道中线15 m范围内.研究结果对北京、成都、沈阳等砂卵石地层盾构施工所诱发振动具有借鉴作用.
    Abstract: Cutter and soil structure interaction, muck and segment transport vehicle, shield equipment were the primary cause of shield construction vibration based on field investigation and preliminary test in Beijing metro line shield tunnels. According to the researches of field investigation and numerical simulation, the following conclusions could be drawn: 1) vibration frequency band caused by cutter is wide, and dominant frequency is concentrated in the range of 20 ~ 90 Hz; 2) vibration amplitude value caused by supporting vehicles is smaller than other factors, and frequency band of vibration amplitude is concentrated in the range of 0 ~ 20 Hz; 3) there is no attenuation in medium high frequency result from the interaction between track and structure. The frequency correspond to vibration amplitude is concentrated in 70 ~ 90 Hz. The frequency will drop below 20 Hz when vibration propagates to the earth surface. Vibration incidence is concentrated in the scope of 15 m from tunnel center line. The researches have reference for the vibration induced by shield construction in sand and gravel stratum in Beijing, Chengdu, Shenyang and so on.
