摘要
根据全断面掘进机在新疆达坂隧洞掘进过程中滚刀的实际消耗情况及更换滚刀频次的观测与统计结果,定性分析了在不同围岩条件下TBM滚刀失效和滚刀更换频次的变化规律及影响因素,为TBM施工滚刀及配件的储备和工程成本控制提供了一定的参考依据。
The variation law and the influence factor of TBM rolling blade losing efficacy and rolling blade changing frequency are analyzed under different surrounding rock according to the observation and statistical result of rolling blade consumption and changing frequency in the advance of Daban tunnel for provide the basis of rolling blade and project cost control.
