Abstract

In general, the tunnel portal is constructed with reinforced concrete. And the carbo- nation of concrete can cause reinforcement corrosion, causing function failure and tunnel destruction. To establish management system such as tunnel inspection and rehabilitation, distance between tunnel portal and coast, service life and traffic were selected as carbonation influencing factors and correlation analysis with carbonation depth for each influencing factor was performed.
