Three tunnel had constructed in shale and sandstone area of the Shimanto formations in Wakayama Prefecture.<BR>Tunnel support patterns of these tunnels were decided by the new rock mass classification of J. H. at cutting face. The crown settle and convergence at part of DI pattern which was decided based on slickensideand fall of rocks at face were 15 or less mm. In these of case, it needs to consider some geological factors for design tunnel support pattern. We study the monitoring and observation method at cutting face for design tunnel support pattern.
