将未确知测度理论与关联函数相结合,用于地下洞室岩体质量评价。根据地下洞室岩体质量的影响因素和分级标准,运用未确知测度理论建立了地下洞室岩体质量评价指标的未确知测度函数,用关联函数确定评价指标的权重,依据置信度识别准则对地下洞室岩体质量进行评价,并结合实例进行了对比分析。研究结果表明,该方法评价过程合理、结果可靠,为地下洞室岩体质量评价提供了一种新方法。
The theory of unascertained measure is combined with the correlation function to evaluate the quality of underground cavern rock mass. According to the influencing factors and grading standards of rock mass quality in underground caverns, the unascertained measure function of rock mass quality evaluation index of underground cavern is established by using the unascertained measure theory. The weight of evaluation index is determined by the correlation function, Criterion is used to evaluate the quality of rock mass in underground cavern and a comparative analysis is carried out with examples. The results show that the proposed method has a reasonable evaluation process and reliable results, which provides a new method for rock mass quality assessment in underground caverns.
