Abstract: The air permeability of soil generally refers to the rate which water diffuses through the soil and airflows through the soil. Currently, underground railroads, largc-scale underground structures and pipelines in developed countries adopt the shield method. Generally, this method needs air pressure to stabilize the digging. Subsurface, therefore it is critical to control the permeability of the soil. This paper is based on the results of the permeability experiment at Taipei basin. The detailed analysis of the results leads to the derivation of the respective permeability.

Key words: permeability of air, permeability of lost air, in-situ test
