摘要：

In this research, Q-logging system was developed based on the cores drilled at the grouting panels to investigate the influence of the cement grouting on the rock mass properties at the Bakhtiary darn site. In this way, rock masses in the different boreholes at the grouting panels were classified using the Q-system. Then, using the experimental equations, rock mass deformation modulus (E-rm) was calculated for each borehole. In order to evaluate this method, value of the rock mass deformation modulus was also obtained by the dilatometer test results. The outcomes display that the Q-logging system can be used as a practical and undemanding method in evaluation of rock mass quality by the grouting treatment. (C) 2014 Elsevier Ltd.
