可液化地层中盾构施工技术

结合在建项目，以南京饱和粉细砂层典型特性为案例，分析可液化地层中盾构法施工可能遇到问题和危害，并总结了一些应对措施，以减少此类地层对盾构隧道工程的影响。

Shield Tunneling Technology in Liquefiable Ground

On basis of the typical property of the saturated fine silty sand ground in Nanjing and the shield tunneling projects under construction, the author analyzes the problems and impacts of shield tunneling in liquefiable ground and recommends some countermeasures so as to minimize the impacts of the liquefiable ground on the shield tunneling.
