| 摘 要： | 基于盾构施工对周围土体及构筑物的扰动影响机理,通过实测数据对盾构近距离穿越扰动影响问题进行了定量分析,并讨论了运营隧道对各盾构施工参数的敏感性.研究结果表明盾构穿越对已建地铁隧道的扰动影响主要以隧道的竖向位移为主.随着盾构推进,隧道结构纵向上呈波浪状,其隆起峰值不断沿推进方向移动.盾尾后隧道段受盾构穿越的影响显著,但隆起峰值始终位于盾尾后.

| Abstract: | Based on the disturbing effect mechanism of shield construction on surrounding soil and buildings, a quantitative study on the disturbing effect of shield construction on adjacent running subway. is carried out by field monitoring data. And the sensitivity of running subway to shield construction parameters is discussed. Research results show that shield crossing mainly causes the vertical displacement of the old subway. With the advancing of shield, the tunnel takes on the shape of wave in the longitudinal section, and the peak value moving along the direction of shield-driving. The part of tunnel behind the tail of shield is affected greatly by shield crossing and the peak value of heave always appears behind the shield tail. |
