Abstract

Successful application of a TBM in a project requires investigations both on the ground conditions and the machine and backup system design features. Adverse rock mass conditions like mixed face condition, water problem, instability of rock have a great role in TBM downtimes and reduce the machine utilization considerably. In this paper, main rock mass properties utilized for the estimation of TBM performance are evaluated and the influence of rock mass properties on the machine utilization are discussed from the perspective of Karaj-Tehran Water Conveyance Tunnel ( lo 1 and 2) These tunnels are located in northwest of Tehran (capital of Iran). Lot 1 or ET-K` (16 km) at the southeast end and Lot 2 or K`-BR (14 km) at the northwest end of the project area. For this reason, detailed engineering geological reports and maps and daily site reports were used. Developed database also contains daily boring time, different rock mass related downtimes, daily
advance and length of bored tunnel in each engineering geological units.
