Abstract
To accurately assess the organizational resilience grade of major transportation infrastructure projects and enhance their capability to cope with emergencies and risks,this paper defines the connotation of organizational resilience for such projects based on resilience theory.Focusing on the four core capacities in the resilience evolution process—resistance,absorption,recovery,and adaptation—and considering the characteristics of highway linear projects such as high environmental exposure and multi-agent collaboration,an organizational resilience evaluation system is constructed from five dimensions:personnel,equipment,management,environment,and emergency response.Based on the variable-weight matter-element extension theory,the closeness-degree criterion is introduced to replace the maximum membership degree principle,and an improved project organizational resilience evaluation model is constructed to enhance the accuracy of resilience grade determination.Based on the evaluation results,key indicators affecting project organizational resilience are identified,including intelligent monitoring equipment coverage rate,accident experience learning capability,and information feedback efficiency.Resilience enhancement strategies are summarized from five aspects:full lifecycle management,equipment technology innovation,professional talent development,environmental defense systems,and emergency linkage mechanisms.Finally,the West Second Ring Expressway project in a certain city is selected for empirical application.The results show that the organizational resilience grade of this expressway project is Level Ⅱ,indicating a relatively high level,but with a tendency toward Level Ⅲ.The evaluation outcome is generally consistent with the actual project conditions,verifying the model's effectiveness.The study constructs a resilience indicator system incorporating smart construction elements and improves the dynamic weight adjustment and discrimination criteria of the matter-element extension model,providing theoretical references and practical tools for resilience evaluation and management of major transportation infrastructure projects.关键词
