摘要
针对岩体质量评价不仅具有随机性,而且具有模糊性和信息不完全性这一特征,本文提出了一种以模糊测度为度量,以[0,1]为评价域的不确定性评价新方法。探讨了新的岩体完整性系数(I_(dc))的概念和计算方法。建立了岩体基本质量定量评价的统计公式和以模糊测度为度量的评价关系式。
In view of the fact that not only the randomness but a1so thefuzziness and ineompleteness of information are inevitable in rockmass quali-fication, a new method for appraising rockmass quality,which is measured byfuzzy measure and based on an evaluation field [0,1], is proposed. The conceptof a new rockmass intactity coefficient and its computing method are also sug-gested. The statistic and fuzzy-measure--based formulas for evaluating rock-mass quality correctively are given.
