Established in 1992 as a non-profit incorporated association, the Korean Tunnelling and Underground Space Association (KTA) is a tunnel-oriented national organization to comply with the international aims of ITA.

The total number of members as of 2012 will be 2,526 and additional 53 corporatemembers are registered so far.

Most of the KTA members are tunnel engineers, but not limited to the civil engineering field and recent expansion into the field of fire, disaster prevention and ventilation within tunnels, among others, are noteworthy.

The KTA has changed its English name from the Korean Tunnelling Association to the Korean Tunnelling and Underground Space Association this year according to ITA.

The KTA is working closely with the Korean government in terms of tunnel-related policies and technologies, and plays a major role in revision of the tunnel specification and standards.

The technical journal of “Tunnelling Technology” is published 6 issues in 2012 and covered 43 papers including awarded paper of “Rock TBM design model derived from the multi-variate regression analysis of TBM driving date”.
