摘要
运用模糊数学法和层次分析法对边坡地质灾害风险进行评价。通过云南公路边坡地质灾害调查结果,分别建立边坡地质灾害影响因素层次分析模型和风险评判集,实现对边坡地质灾害风险的模糊综合评判。将边坡地质灾害风险评价方法应用于宜昭高速公路边坡的风险评价中,得到各边坡的风险级别,边坡风险评价结果与实际边坡失稳情况基本一致,验证了基于模糊综合评判的边坡地质灾害风险评价方法的有效性。
The risk evaluation of slope geological disaster is implemented by using fuzzy mathematics and analytic hierarchy process method.Through the investigation results of Yunnan highway slope geological disaster,the analytic hierarchy process models and risk evaluation sets of influencing factors of slope geological disaster are established respectively to realize the fuzzy comprehensive assessment of slope geological disaster risk.The proposed slope geological hazard risk assessment method is applied to the risk assessment of Yizhao expressway,and its risk grade of each slope is obtained.The slope risk assessment results are basically consistent with the actual slope instability,which verifies the effectiveness of the slope geological hazard risk assessment method based on fuzzy comprehensive evaluation.
