TL;DR: In this article, the authors proposed a new TBM performance prediction model based on a database of actual machine performance from different hard rock TBM tunneling projects, and analyzed the available data and offer new equations using statistical methods, relationships between different geological and TBM operational parameters were investigated.

TL;DR: In this paper, the authors present an overview of the Karaj Water Conveyance Tunnel (KWCT) operation and review the results of field performance of the machine, including analysis of available data including geological and geotechnical information and machine operational parameters, actual penetration and advance rates compared to the estimated machine performance using prediction models, such as CSM, NTNU and QTBM.

TL;DR: The Nowsood water conveyance tunnel is 49 km long and has been designed for transferring 70m3/s water from Sirvan river southward to Dashte Zahab plain in the west of Iran as mentioned in this paper.

TL;DR: In this article, a new empirical model for predicting cutter wear in moderate to very strong pyroclastic and mafic igneous rocks based on data collected from a long tunnel constructed by mechanized method in Iran.

TL;DR: The central part of the Zagros Fold-Thrust Belt is characterized by a series of right-lateral and left-linear transverse tear fault systems, some of them being ornamented by salt diapirs of the Late Precambrian-Early Cambrian Hormuz evaporitic series as mentioned in this paper.
