基于ANP的盾构施工风险模糊综合评判

Fuzzy Comprehensive Evaluation of Shield Construction Risk Based on ANP

针对盾构施工风险评估中客观存在的评价指标相互影响问题,构建了基于网络层次分析法(ANP)的模糊综合评判模型(ANP-FCE模型),采用工程案例并结合专家调查阐述了模型的算法,旨在解决评价指标之间相互依存和反馈问题。运用模型对成都地铁4号线凤溪-南熏区间的盾构施工风险进行评价,结果与工程实际状况吻合。研究结果表明:基于ANP的风险模糊评估模型较其他风险评估方法更科学、更合理,可为其他类似工程制定风险防控措施提供依据。

With respect to the mutual influence of objective evaluation indexes in shield construction risk assessment,a fuzzy evaluation model based on ANP is constructed in this paper.The engineering case and expert investigation are used to expound the algorithm of the model,aiming at solving the interdependence and feedback between evaluation indexes;the risk assessment results of the shield construction of Fengxi-Nanyan section of Chengdu Metro Line 4 by using the model are consistent with the actual conditions of the project.The research results show that the ANP-based risk fuzzy assessment model is more scientific and reasonable than other risk assessment methods,which can provide a basis for the development of risk prevention and control measures for other similar projects.
