In order to evaluate the quality of rock mass scientifically and effectively,the cloud model theory is introduced and a comprehensive evaluation model of rock mass quality of underground engineering based on game theory-cloud model is constructed.Firstly,six typical influencing factors are selected from three aspects,including strength factor,integrity factor and geological factor,and a comprehensive evaluation index system of rock mass quality is constructed;Secondly,the comprehensive weight is calculated by game theory,and the rock mass quality grade is comprehensively judged based on the principle of maximum membership degree by calculating the single index membership degree and comprehensive certainty degree;Finally,taking a gold mine as the research background,four typical regional rock masses are selected for relevant calculations.The results show that the evaluation results of the model are consistent with the reality,and can provide a new quantifiable idea for the evaluation of rock mass quality.
