Discrete-Element Analysis of the Excavation Performance of an EPB Shield TBM under Different Operating Conditions

Discrete-Element Analysis of the Excavation Performance of an EPB Shield TBM under Different Operating Conditions

This study used a discrete-element analysis to predict the excavation performance of a 7.73 m-diameter earth pressure balance (EPB) shield tunnel boring machine (TBM). The simulation mainly predicted several excavation performance indicators for the machine, under different operating conditions. The...
