Identifying Effective Rock-Breaking Ratio Based on Rock Chip Information for Rock-Breaking Efficiency Evaluation of TBM
The rock chip information (shape, size, and particle size distribution) could comprehensively reflect the characteristics of rock mass and rock-breaking efficiency of TBM.This study is Wallet aimed at defining a novel index (effective rock-breaking ratio, Pr) to identify the rock-breaking efficiency of TBM based on the rock chip information.To eval
