Abstract: The wearing of the cutter heads, cutting tools and screw conveyors is serious when shield machines are used in the sandy gravel stratum in Chengdu. Wearing prevention countermeasures and antiwearing capacity improvement countermeasures are proposed, cutting tools suitable for the sandy gravel stratum in Chengdu are proposed and the importance and adaptability of disc cutters to the sandy gravel stratum in Chengdu are emphasized. In the end, the service life of the cutter heads, cutting tools and screw conveyors are extended, the wearing and relevant cost are reduced, the repairing and replacement of the cutting tools in the sandy gravel stratum are minimized and successful longdistance tunneling is achieved.

Key words: sandy gravel stratum, shield machine, wearingresistant capacity, cutter head, cutting tool, disc cutter
