摘要
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。
Uncertainty measure theory and dependent function are combined rationally and then applied to evaluating underground cavern rock quality. According to influence factors and grading standards of underground cavern rock quality, uncertainty measure functions of evaluation indices are obtained using the uncertainty measure theory. Dependent function is used to calculate weights of the evaluation indices of underground cavern rock quality. Credible degree recognition criteria are used to evaluate underground cavern rock quality. Finally, the comparative analysis is made with examples. The results show that the uncertainty measure method is reasonable and reliable; and it is a new method for evaluating underground cavern rock quality.
