Study on Stabilization of Tunnel Foundations Built on Collapsible Loess

Abstract:

Loess soils always have lower dry densities, open structures and joint fissures, and could exhibit a significant decrease in volume due to their collapse when wetted. These soils pose potential threat on structures built on them. When a tunnel built on such soils, the bearing capacity of tunnel foundation could not always meet requirements of structural stability, and therefore need some improvements. The improvements of collapsible loess foundation include cement compaction piles and root piles.
