title = "The performance of a roadheader in high strength rock formations in K{\"u}{\c c}{\"u}ksu tunnel",
abstract = "The main objective of this study was to investigate the performance of a roadheader used for the excavation of K{\"u}{\c c}{\"u}ksu Sewage Tunnel having a length of 1037.52 m. The tunnel is located in Anatolian part of Istanbul and constructed by STFA for Istanbul Water and Sewerage Administration (ISKI). Detailed statistical analysis showed that net advance rate of the roadheader is directly influenced by rock compressive strength, rock mass quality designation and water income. In the second stage of the research study, a big rock block taken from the tunnel face was subjected to full-scale rock cutting tests in the laboratory using a linear cutting machine. Cutter force and specific energy values were recorded for different depths of cut and cutter spacings and likely net cutting rate of the roadheader excavating rock formation was predicted using specific energy and cutter head power. In situ cutting rate and laboratory predicted values were compared in order to test the validity of the full scale rock cutting tests.",
