				Estimation of the BQ system and rock mass modulus based on the P-wave velocity of the rock mass: a case study from the Himalayas tunneling - Environmental Earth Sciences
The classification of rock mass quality is essential for geotechnical and engineering applications. Commonly used classification methods include the Rock Mass Rating (RMR), the Q system, the Geological Strength Index (GSI), and the Basic Quality (BQ) system. Among these, the BQ system has been...
