The doubleshield TBM applied in urban metro construction is always accompanied by difficulties such as difficult launching, limited small radius, crossing extremelyhard rock and fault and fracture zone. Hence, the problems and countermeasures for doubleshield TBM applied in Shenzhen Metro construction are studied. Four aspects are proposed as follow: (1) Cutting tool wear and consumption rules, advancing control measures and solution of measuring platform vibration in the construction of doubleshield TBM with limited small turning radius about 260 m; (2) a separate launching technical scheme solving the problem of limited space; (3) targeted design of doubleshield TBM and improvements for cutting tool under 210 MPa extremelyhard rock condition; (4) tunneling parameters and countermeasures for doubleshield TBM crossing fault fracture zone.
