基于IAHP扩展TOPSIS法引水隧洞实时风险识别

Real-time safety risk identification of water diversion tunnel based on IAHP and extended TOPSIS methods

基于区间层次分析(IAHP)法和扩展逼近理想解排序(TOPSIS)法,建立了合理的引水隧洞实时安全风险识别模型,通过在某大型引水工程接近城区隧洞段中的运用,在不同施工阶段做出安全风险区间多指标决策,并根据相应阶段的工程数据对安全风险因子进行排序,检验了实时安全风险识别模型的可行性和有效性。

Based on the interval analytic hierarchy(IAHP)method and the extended approximation ideal solution sequencing(TOPSIS)method,a reasonable real-time security risk identification model was established.The proposed model was employed in the risk analysis of a large-scale water diversion project near the urban tunnel section.The multiple-index decisions were made on the number of safety risk intervals at different construction stages.According to the engineering data of the corresponding stage,the safety risk factors are sorted.The feasibility and effectiveness of the real-time security risk identification model was tested.
