Developing Estimation Equations for the Cerchar Abrasivity Index of Rocks Applicable to TBM Tunnels

Rock abrasivity plays an important role in the machine design, construction scheduling, and budgeting of TBM projects. Establishing several faster and simpler estimation equations for the Cerchar Abrasivity Index (CAI) of rocks is, therefore, very important. This study investigated the correlation b...
