Selection of cutter type for difficult ground conditions
The range of cutter types used in TBMs in terms of the cutting efficiency in difficult grounds is outlined in this chapter. First, a summary of the comparative study of V‐ and CCS‐type disc cutters is given for a double shield TBM intended to be used in the Dragos sewerage tunnel in Istanbul. It is concluded that V‐type disc cutters are more efficient in terms of cutter force than CCS disc cutters, but CCS cutters are preferred in practice since they are more resistant to abrasive characteristics of the rocks and lasted longer than the V‐type discs. The methodology for changing disc cutters to chisel cutters in the Beykoz–Istanbul Tunnel and the inefficiency of using the tungsten carbide studded disc cutters in Marmaray–Istanbul project are discussed in this chapter.
