摘　　要：针对传统岩体质量评价方法所存在的缺陷,将博弈论和密切值法相结合,用于水电站岩体质量评价。根据水电站岩体质量的分级标准和影响因素,运用密切值法建立岩体质量评价模型,依托博弈论的指标赋权法明确对应指标权重,最后根据密切值的分析结果对岩体质量进行评价,并结合实例进行对比分析。研究结果表明:基于博弈论的组合赋权法确定的组合权重不仅科学合理而且有效克服了密切值法权重计算的主观性;另一方面,采用密切值评价方法对岩体质量评价获得的结果与变权欧式距离评价方法结果比较,结果完全一致,与可拓学理论、未确知测度理论评价结果比较也基本相吻合,具有一定的工程实用价值,可以运用于水电站地下洞室岩体质量评价中。In view of the shortcomings in the traditional rock mass quality evaluation methods,to use game theory and the osculating value method,underground hydropower station cavern rock mass quality evaluation.According to the rock mass quality classification standard of the underground cavern and influencing factors,by using osculating value method of rock mass quality evaluation model is established,based on the optimal combination of the game theory method to determine the index weight,finally according to the size of the osculating value to evaluate the rock mass quality,and combining with the example is analyzed.The results show that the methods based on the combination of game theory determine the combination of weight not only scientific and reasonable and effective overcome the subjectivity of osculating value method of weighting;on the other hand,compared with the result of variable weight euclidean distance evaluation method,the result of rock mass quality evaluation by using osculating value evaluation method is completely consistent,the evaluation results are in good agreement with those of extension theory and unascertained measure theory,which has certain engineering practical value and can be used in the evaluation of rock mass quality of underground cavern of hydropower station.
