During shield tunneling in composite stratum, especially in granite stratum with high rock strength and high-water content, the abnormal damage of disc cutter is frequent. This paper analyzes the law of wear of disc cutter and obtains the wear coefficient, and then predicts the number of disc cutters needed for shield machines in tunneling section and reduces the number of disc cutters needed, so as to reduce the extra cost of shield construction.
