Abstract：Aiming at the high-risk issues caused by busy shipping routes，vesel interference，and dense facilities in inland waterway bridgeconstruction，the traditional FuzzyAnalytic HierarchyProcess（FAHP）haslimitations in subjective judgment and insufficient considerationof keyrisk factors，making theriskassessment results inaccurate.Improvesthe traditional FAHPby introducing nonlinearoperatorsand set-valued statistical methods，comprehensively modifying risk weights and fuzyrelationship matrices，andquantifying the nonlinear relationships between indicators to reduce subjective biasand improve the capture of complex risk factors.Applying this method to theconstruction scheme analysis of an inland waterwaybridge，theresults showthat its assessment results have higher consistency with theactual siteconditions.The improvedFAHPcan more comprehensivelyreflectcomplexconstructionrisksandeffectivelysolve the problems of strong indicator subjectivityand insufficient nonlinearrelationship proessing.Itcan provide valuable reference for scheme optimization and risk control in similar projects.
