Abstract: The real-time monitoring of the cutter wear was realized during TBM tunneling by installing a cutterhead working status monitoring system on the cutterhead of TBM in the tunnel section of the second bid, the Chaoer River to Xiliao River Water Conveyance Project. The whole life wear process curve for a single cutter was obtained on basis of the monitored data. The wear process of a single cutter could be divided into three stages, namely low cutter wear rate at the initiation stage, acceleration cutter wear stage and uniform cutter wear stage. The cutter edge shape had a significance impact on the cutter wear curve. Based on the rock mass conditions recorded during TBM tunneling process, combined with TBM operating parameters and monitoring data, the influence of the rock mass parameters and TBM operating parameters on the cutter wear rate was analyzed. The results showed that the cutter wear value per unit broken rock volume was suitable to measure the cutter wear rate, and the rock abrasivity, rock mass integrity and field penetration index were the key parameters to affect the cutter wear rate, which could provide a basis for the accurate cutter wear prediction model in the future research.
