Field Test Study of the Artificial Ground-Freezing Method Subsurface Excavation Construction of Watered Sandy Stratum in Collapsible Loess Area
Saturated sandy stratum often makes tunnel excavation exceedingly difficult owing to its high water content. The artificial ground-freezing (AGF) method is an effective way to reduce the construction risks in such stratum; however, the AGF mechanism in the saturated sandy stratum of a collapsible lo...
