摘　　要：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。Project risk assessment is a rather complex work, which includes many uncertain factors. Hence, it is different for an accurate comprehensive assessment using quantitative method. In view of complexity, fuzziness and lacking of reasonable evaluation method for assessment object, with project case the paper selecting primary indicators which affects project risk, applies for AHP to determine index weight at all levels which is used for fuzzy comprehensive evaluation. Analysis shows that fuzzy comprehensive evaluation method to be used for project risk assessment is feasible, the outcome is consistent with the mechanical calculation, which objectively reflects comprehensive assessment value influenced by the indicators, so it possess specific advantages.
