Bond-Slip of Connecting Bolts Between Tunnel Segments and Metro Station Portal Ring Beam

  • 摘要:

    地铁车站洞口的混凝土环梁与隧道管片之间一般通过螺栓连接,螺栓往往以预埋的方式锚入车站环梁内,并且与握裹它的混凝土之间存在粘结-滑移变形,这对环缝张开宽度和环梁结构损伤发展都可能产生影响,为进一步明确其中的机理及影响程度,参考既有的粘结-滑移本构模型,利用可细化分析粘结-滑移的有限元分析平台,在充分考虑材料非线性特征的基础上,针对3种不同型号螺栓,分别考虑锚固长度足够和不足两种情况,分析了螺栓在环梁内的粘结-滑移,以及环缝宽度增大的过程;通过量化分析粘结应力和螺栓应力沿螺栓长度的分布,揭示了粘结-滑移对环缝宽度发展的影响机制. 分析表明:采用粘结-滑移模型时,得到的螺栓连接刚度介于嵌固模型和弹簧模型之间,粘结-滑移变形对盾构管片和车站环梁之间环缝宽度的影响不可忽略;仅考虑受拉影响,即便在锚固长度足够的情况下,当螺栓接近屈服时,螺栓与环梁间的粘结-滑移变形在环缝张开宽度中占比最大可达30%,螺栓屈服后,这个滑移占比会随环缝扩展降至8%以下,受此影响,考虑粘结-滑移的螺栓抗拉刚度最低约为完全嵌固模型的1/3.
