| 摘 要： | 软土地区盾构近距离穿越已建隧道的工程近年来不断增加,尤其是运营中的地铁隧道其结构安全保护要求很高。在地铁不停运过程中,相邻穿越施工中稍有不慎都可能引发巨大的安全事故。穿越施工对地层及相邻隧道结构扰动的因素众多,机理复杂。本文归纳了国内目前类似施工的控制指标,对该类工程的研究现状、变形机理及影响因素进行了探讨。

| Abstract: | Recently,more and more tunnels need to cross above or beneath the existing metro line in soft soil. It's very possible to cause significant security incidents by close shield tunneling when adjacent metro train is running. There are many influential factors on the stratum and built tunnel structure,furthermore,the mechanism is very complex.The paper summarized the protection requirements.The research status,displacement mechanism and influence factors were analyzed. |
