Abstract

Rock mass classification systems are widely used in engineering applications at the preliminary design stages. When sufficient information is not available, utilization of the rock mass classification systems is useful to compile a more complete understanding of the compositions and characteristics of rock masses in project sites. In this research, the engineering characteristics were assessed for the rock masses of Darband dam site in North Khorasan province, northeast of Iran. The properties are resulted from site investigations as well as laboratory experiments using eight classification systems. Field investigations include engineering geological mapping, intensive discontinuity surveying, core drilling, and sampling for laboratory testing. Thus, rock quality designation (RQD), rock mass rating (RMR), rock tunneling quality index (Q), slope mass rating (SMR), weakening coefficient (WC), geological strength index (GSI), rock mass index (RMi), and dam mass rating (DMR) were used for assessing the rock masses in both right and left abutments of the Darband dam site. The rock masses were classified into various classes, so that based on the RQD, Q, and WC classifications, the rock mass of the right abutment is more stable than left abutment, whereas, according to the RMR, SMR, GSI, DMR, and RMi systems, the left abutment rock mass has better quality. Overall, the selected rock mass classifications revelated similar results and they were coordinate to each other. As a useful finding, the rock mass in the right abutment is weaker than the left abutment and there is the possibility of instability.
