Abstract

NATM has been applied most of tunnel design and construction in Korea these days. But, if you observe the tunnel designing method and construction conditions, you can see that the NATM isn's usually the most suitable to Korean geology. Also most of engineers feel that it is necessary to understand the NATM correctly adn to introduce another tunnelling principle which can be applied more economically and safely. So, we'd like to introduce a new tunnelling concept. Norwegian Method of Tunnelling(NMT) by comparing the NATM. The main character of NMT is that the forward prediction of conditions and the support of tunnel is done through geological investigation in details. And it can be compared with NATM, in which the support pattern is decided by monitoring of tunnel deformation on the construction.
