  Study on Comparative Analysis of TCI and Crack Classification

  The civil engineering infrastructures in Japan were constructed intensively between the period of high economic growth. The ageing of these civil engineering structures will require appropriate maintenance to ensure their safety. In particular, various methods have been proposed to evaluate the health of the tunnel-lining of road tunnels. One of them is the Tunnel-lining Crack Index (TCI) proposed by one of the authors, which makes it possible to quantitatively evaluate the status of crack distribution on a tunnel-lining. The purpose of this study is to propose a criteria for quantitative measures of tunnel integrity. A comparative analysis was conducted between the judgment categories used by engineers to qualitatively judge cracks in the lining and TCI and increase in TCI, and the relationship between the judgment categories and the increase in the width and length of cracks was examined.
