The　HuaiFu　tunnel　section　of　Shenzhen　Metro　Line　12　is　located　in　Baoan　District,　Shenzhen,　with　a　total　length　of　approximately　1750　m.　The　excavated　grounds　are　extremely　complicated,　with　soft　soil　ground,　mixed　ground,　fault　zones,　and　hard　rock　ground　with　a　length　of　over　1200　m.　A　dual-mode　shield　TBM　with　EPB　and　single-shield　modes　was　employed　in　the　tunnel　section.　To　evaluate　the　tunnelling　performance　of　the　dual-mode　shield　TBM,　two　sets　of　monitoring　systems　were　applied　to　acquire　the　cutterhead　working　performance　during　the　dual-mode　shield　TBM　tunnelling,　and　the　tunnelling　difference　between　the　dual-mode　shield　TBM　and　composite　EPB　shield　in　hard　rock　ground　were　analysed.　As　for　the　cutterhead　working　performance,　relative　sliding　occurred　between　the　cutter　and　tunnel　face,　and　the　cutter　wear　curve　increased　linearly　in　any　ground　and　excavation　modes.　Under　different　grounds　and　excavation　modes,　the　cutterhead　temperature　thresholds　were　different,　and　the　time-domain　and　frequency-domain　of　the　cutterhead　vibration　were　different.　As　for　the　tunnelling　difference,　the　single-shield　mode　offered　a　higher　penetration　rate,　fewer　cutter　replacements,　lower　energy　consumption　and　faster　advance　rate　than　the　EPB　mode.　The　advance　rate　of　EPB　mode　was　higher　than　that　of　the　composite　EPB　shield　due　to　the　faster　cutterhead　rotation　speed.　The　results　can　provide　guidance　for　excavation　mode　selection　of　the　dual-mode　shield　TBM　and　type　selection　of　TBM　for　similar　grounds.
