摘要
根据岩体质量的影响因素和分类标准,运用改进的灰色关联分析法建立岩体分类模型,由改进层次分析法确定影响岩体分类的各指标的综合权重,依据关联度对岩体进行分类。这种基于改进的灰色关联分析法和层次分析法相结合的岩体质量分析的综合方法,克服了传统层次分析法中权重的确定过于主观和传统灰色关联分析法中没有考虑岩体质量分类标准中的区间形式的缺点,评价结果与工程实际更加相符。
Based on the influencing factors and classification standard of rock mass quality, the classification model of rock mass quality is established by using improved grey correlation analysis, then the weight values of influencing factors are determined by using improved analytic hierarchy process, and finally the rock masses are classified by associate degree. This method overcomes the defects which the weights computed by traditional AHP are not objective and the interval of grade standards is not taken into account in traditional grey correlation analysis. The evaluation results of an engineering example are more line with actual engineering.
