摘　　要：以北京地铁14号线将台路站饱和粉细砂～中粗砂层暗挖通道为例,阐述了水平导向高压喷射注浆工法在饱和粉细砂层地铁修建中的应用。实践证明,该方法既能规避不安全环境,又能有效起到止水效果,为同类项目施工提供了借鉴作用。Taking the example of underground channels of 14 -line in Beijing subway in saturated fine sand-medium sand layer, the paper illustrated the application of horizon-oriented high pressure jet grouting method in the subway construction in saturated fine sand-medium sand layer. The practice shows that this method can not only avoid unsafe conditions, but al- so can stop water.
