摘　　要：为确保桥梁工程施工安全生产投入有效落实,首先利用灰色关联法(GRA)分析项目监理机构和施工单位施工安全行为影响因素的关联度,并确定核心致因要素;然后,构建系统动力学(SD)模型分析各核心致因要素之间的相互作用机制;最后,分析影响施工安全行为的核心致因要素的脆弱性和韧性。结果表明:施工单位两极化罚款、项目监理机构高额监管成本、双方较低的初始比例是桥梁工程施工安全行为的脆弱点;适度的经济罚款和监管成本以及加大培训提高一线人员的安全意识,对提升施工安全行为韧性具有明显效果。To effectively implement safety production investment in bridge construction projects,GRA was used to analyze the correlation between the influencing factors of construction safety behavior from both the project supervision organization and construction units,and then the core causal factors were determined.Subsequently,a SD model was proposed to investigate the interaction mechanisms among the core causal factors.Finally,the vulnerability and resilience of the core causal factors affecting construction safety behavior were analyzed.The results indicated that extreme fines imposed by construction units,high supervision costs for project monitoring organizations,and low initial proportions between parties were the key vulnerability factors of the safety behavior in bridge construction.Reasonable economic fines,appropriate supervision costs,and enhanced training to improve frontline personnel's safety awareness significantly improved the construction safety behavior resilience.
