摘要
根据边坡工程所具有的不确定性、模糊性特点,基于AHP-FUZZY方法对公路边坡的稳定性进行定量评价。根据工程地质资料整理汇总选取了4类15项评价因子进行层次分析,确定评价因子权重,经过二级模糊综合评价向量确定边坡稳定性。研究结果表明边坡实际情况与法评判结果基本吻合。该方法简便可行,结论可靠,具有一定的优越性,可为公路边坡稳定性分析提供参考依据。
Because of the uncertainty and fuzziness of slope engineering, highway slope was quantitatively evaluated based on the AHP-FUZZY. According to the engineering geological data, 15 items were selected for analytical hierarchy process, determining the weights of evaluation factors. After two grade fuzzy comprehensive evaluation vector, the final slope stability was determined. The results show that the actual failure of the slope coincides with the results of the method. The method is simple and feasible, and the conclusion is reliable and has certain advantages. It can provide reference for the stability analysis of highway slope.
