  Problems Encountered in a Large Tunnel Excavated inGraphite Schists

  Abstract: The T34 tunnel constructed within the scope of Ankara Istanbul High Speed Train Project. During the T34 tunnel excavation, deformations of up to 58 cm occurred between Km: 230+830 - 230+708. These deformations are far above tolerance and caused the failure of tunnel supports. When the deformation measurements were investigated, it was observed that the deformations resulted in the closure of...

  Squeezing Mechanism in a Large Tunnel Constructed i n Weak Rock Mass

  Abstract: Unexpected and severe deformations occurred during the excavation in the T15 tunnel constructed in Ankara-İstanbul High Speed Railway Project. As a result of these deformations, failures occurred in the tunnel supports and the tunnel lost its stability. Deformations occurred between Km: 191 + 080 - 191 + 300, and 50 cm deformations were measured. Due to the closures, cracks occurred in the...
