摘要：

The　rock　samples　in　different　marble　rock　types　were　taken　along　the　headrace　tunnel　excavated　by　Tunnel　Boring　Machine　of　Jinping　II　Hydropower　Station.　The　author　used　the　taken　samples　to　carry　out　Cerchar　abrasivity　tests　indoors.　Then　the　CAI　values　were　analyzed　and　evaluated.　By　analysis　of　the　cutter　wear　of　TBM,　the　author　expressed　his　opinion　that　the　cutter　wear　in　different　marble　rock　types　is　low.　These　results　accord　with　the　abrasivity　tests　results　of　marbles.　But,　the　abnormal　cutter　breakage　is　very　high.　It　is　mainly　related　to　the　uneven　tunnel　face.
