通过对盾构刀具磨损的原因分析和寿命计算,可以预测盾构在隧道开挖区间刀具是否需要更换以及需要更换的次数。并通过算例说明刀具寿命预测的分析方法。
Through the analysis of the wear and tear of the shield tool and life calculation, we can predict whether the shield tool needs to be replaced and the number of replacement needs in the tunnel excavation interval. An example is given to illustrate the analysis method of tool life prediction.
