As the key project of a hydropower station,the safety of a water diversion tunnel will impact directly normal benefits and serving life of the power station. Based on this,this paper is to establish a risk evaluation model of tunnel landslide with the efficacy coefficient method,combined with the basic contents of tunnel landslide risk influence factors,to divide variables into interval type,stable type,extremely large type and extremely small type,afterwards,to solve each coefficient with single efficacy,and to analyze the index weight coefficient with game theory,finally,to obtain the coefficient of total efficacy. This study verified the suitability and reliability of the model with a water conservancy project in Bijie City as the example.
