摘要

Disclosed is a geotechnical bedrock classification method of a cataclastic rock. The present invention comprises the following steps: estimating rock quality designation (RQD) and joint set number (Jn) of the bedrock on a tunnel face; computing RQD/Jn; classifying a geological condition and Is_50 index to classify the bedrock depending on a range of estimation values of computed RQD/Jn.;COPYRIGHT KIPO 2017
