摘要
根据全断面隧道掘进机在秦岭隧道（出口段）初始３６８８ｍ掘进中刀具的实际磨损情况，分析了掘进机在混合花岗岩和混合片麻岩两种不同岩石类型地质条件下刀具的磨损规律；提出了掘进机及其刀具选择、使用注意事项，以及对刀圈研究、设计、制造的要求，对于ＴＢＭ及其刀具的设计、制造的改进和合理使用具有重要意义。
On the basis of actual cutter wear condition during the TBM boring of Qinling tunnel(the boring length is 3688m from the south portal),this paper analyzes the cutter wear characteristic of TBM in different geological conditions(the rock types are granite and gneiss).Consequently,the consideration at the time when select,use TBM and cutter is put forward.At the mean time,the requirements of cutter design,manufacture and research are proposed.
