滑坡风险评估是一项相当复杂的工作,包含有很多不确定因素,因此很难用定量的方法准确的进行综合评估。鉴于评估对象的复杂性、模糊性和缺乏合理评价方法,结合工程实例选取影响滑坡灾害风险的主要指标,运用层次分析法确定各级指标权重,并将其用于模糊综合评判中。分析表明:模糊综合评判法用于对滑坡灾害风险评估是可行的,并将该结果与采用力学参数计算结果进行比较是相吻合的,而且该法能客观地反映评价指标对综合评估值影响的强弱,具有特有的优越性。 Landslide risk assessment is a rather complicated task that involves many uncertainties, making it difficult to accurately and quantitatively evaluate a comprehensive assessment. In view of the complexity, fuzziness and lack of reasonable evaluation methods of evaluation object, the main indexes that affect the risk of landslide hazard are selected in combination with engineering examples. The analytic hierarchy process is used to determine the weight of indicators at all levels and used in fuzzy comprehensive evaluation. The analysis shows that fuzzy comprehensive evaluation method is feasible for risk assessment of landslide hazard and the result is in good agreement with the results of mechanical parameter calculation. And this method can objectively reflect the influence of evaluation index on the comprehensive evaluation value Strong or weak, with unique advantages.
