摘要
建立了公路隧道岩体分级的模糊综合评判法。对《公路隧道岩体分级标准》数据进行了分析和整理,确定了适宜的分级指标和分级标准;对评价论域进行了模糊处理,以适应评价指标交叉的要求;建立了各定量和定性指标对不同论域等级隶属度的计算方法;确定了权重选取标准;给出了模糊综合评判的计算步骤;针对韩家岭公路隧道现场实践,进行了现场隧道围岩分级的模糊综合评判,对评判结果进行了分析。
A fuzzy synthesis assessment method of rock mass classification of highway tunnel was established. Data in criterion were analyzed and arranged. Proper classification indexes and their standards were given. The fuzzy treatment to assessment sets was performed for fitting crossed indexes. The calculation method for subordinate degrees to different set grades of different quantitative and qualitative indexes was built. The selection standard of weight was deterinined. The calculation ＇steps of fuzzy synthesis assessment were given. Here, the surrounding rock in Hanjialing highway tunnel was classified by fuzzy synthesis assessment method, and assessment results were analyzed.
