摘要(Abstract):
交通密集水域事故频发,为揭示其安全风险演化规律,明确风险监控重点,以长江口水域为例进行了交通安全风险演化脆弱性分析。基于该水域交通事故案例,运用事件链分析技术构建了安全风险演化网络并解析其拓扑特性;提出了安全风险演化脆弱性概念,运用MATLAB仿真技术进行了定量评价;提出了一种关键脆弱因素辨识方法,并以演化网络为例验证了其可行性。结果表明:长江口水域交通安全风险极易传播扩散,少数关键因素失控易导致交通事故;船员违规违章、船员不合格不适任、强潮汐急潮流等风险因素对该水域交通安全风险演化起到关键作用。研究表明,提出的辨识方法合理可行,可适用于其他交通密集水域,为海事部门精准防控关键风险提供理论依据。
