title = "Successful tunneling through a very weak conglomerate",
abstract = "This article highlights the geotechnical challenges faced during design and construction of Lot No. 6 of the Dez-Qomroud water transfer tunnel project in Iran. The main stratum along the tunnel path is a mud-supported weak conglomerate. Results from comprehensive rock mass characterization using different rock mass classification systems revealed that because of very weak strength properties of the conglomerate some tunnel sections will be stable for not more than ten hours. Some engineering geological considerations made to guarantee a safe construction of the tunnel such as reducing the tunnel diameter and relocating the tunnel route to avoid saturated ground. Implementing results from this study led to successful completion of the project.",
