Abstract

Tunnel support patterns is decided by a geological condition which is estimated by geological survey and these support patterns are change based on the results of cutting face observation and tunnel monitoring at tunnel construction. The authors applied the new system of rock mass classifications which JH made to some tunnel and compared the rock mass classification proposed by this system with the results of electric prospecting, blasting powder volume, and so on. Consequently it is showned that this new system is also very useful in the stage of geological survey and reduces the differences between the designed and adopted support patterns.
