- Abstract
In order to solve the tunnel construction problems such as low efficiency and high consumption of rock tunnel boring ma, chine (TBM) in high-strength and high abrasion hard rock stratum, cutter head trapped in fault fracture zone stratum, and shield stuck in high stress extrusion stratum. Based on the interaction between TBM disc cutter, cutter head, shield and tunnel surrounding rock, through the statistical analysis of multiple TBM method tunnel engineering data, the functional relationships between disc cutter penetration index and rock mass characteristic index, disc cutter crushing volume wear rate and rock mass characteristic index, TBM equipment utilization and fault width, relative deformation of surrounding rock and strength stress ratio were revealed, and the multi-dimensional TBM adaptability evaluation method was established, which was based on disc cutter excavability and abrasion resistance, the risk of cutter head trapped and shield stuck. The research results provide a quantitative basis for TBM construction method selection, equipment design and solution of construction problems in complex geological tunnels. [ABSTRACT FROM AUTHOR]
