| 摘 要： | 城市地铁工程多数由盾构隧道作为连接通道,将沿线车站连成线路,最终形成复杂的轨道交通网.本文以软土地层盾构隧道施工对土体的扰动变形及控制为研究对象,从盾构施工对土体扰动机理、施工扰动影响分区及控制措施、Peck影响分区及工程案例等方面来详细论证,研究成果可为类似工程提供经验借鉴.

| Abstract: | Most of urban subway engineering are connected by shield tunnels,which connect the stations along the line,and eventually form a complex rail transit network.This paper takes the disturbance deformation and control of shield tunnel construction in soft soil layer as the research object,and demonstrates in detail from the aspects of the disturbance mechanism of shield construction on soil,construction disturbance influence partition and control measures,Peck influence partition and engineering cases.The research results can provide experience and reference for similar projects. |
