饱和粉细砂地层隧道处治对策研究

摘要

According to the quicksand phenomenon of tunnel construction in saturated fine sand layer,this paper elaborated in detail each emer-gency countermeasure and tunnel reinforcement countermeasure of a tunnel after quicksand and surface collapse in saturated fine sand layer,could provide reference for similar engineering.%针对饱和粉细砂地层中修建隧道时易发生流砂的现象，详细阐述了某隧道在饱和粉细砂地层中发生流砂及地表塌陷后的各项应急处理措施和洞内加固处理对策，可为类似工程提供参考依据。
