Abstract

  In case of the underground flood way constructing by Shield driven Tunnelling Method with RC segment, the watertightness of the RC segment against inner water pressure had not been studied well, regarding the validity of the conventional crack width calculation formula and the relationship between the crack width and the leak water. In this paper, new formula is proposed and the relationship is exhibited by means of full-size RC-segment loading tests and leak water tests. As a result, the maximum interval of the cracks should be used the interval of the assembly steel bars, and the crack width of about 0.1mm is not leakable in long term, are shown.
