Hazardous chemical logistics and transportation accidents are the main type of port safety accidents. Correctly and objectively analyzing the causes of port hazardous chemical logistics safety accidents and the coupling mechanisms of risk generation are very important for reducing the occurrence of port hazardous chemical safety accidents. Based on the causal mechanism and coupling principle, in this paper, we construct a risk coupling system for port hazardous chemical logistics and analyze the coupling effects in the risk system. More specifically, a personnel-ship-environment-management system is established and the coupling between the four systems is explored. Taking Tianjin Port as an example, the risk coupling factors are analyzed in combination with system dynamics simulation. Under dynamic changes in coupling coefficients, the change of coupling effects are explored more intuitively, the logical relationships between logistics risks are analyzed and deduced, a comprehensive view of the coupling effects and their evolution process in accidents is provided, and the key causes of accidents and their coupling risk effects are identified. For port hazardous chemicals logistics safety accidents, the presented results not only allow for effective analysis of the causes of safety accidents, but also provide reference for the formulation of prevention strategies.
危险化学品物流运输事故是港口安全事故的主要类型。正确、客观地分析港口危险化学品物流安全事故的原因及风险致生的耦合机理，对于减少港口危险化学品安全事故的发生具有重要意义。基于致因机理与耦合原理，本文构建了港口危险化学品物流风险耦合系统，并对风险系统中的耦合效应进行了分析。具体而言，建立了人-船-环境-管理系统，探讨了四个系统之间的耦合。结合系统动力学仿真，以天津港为例，对风险耦合因素进行了分析。在耦合系数的动态变化下，更直观地探究了耦合效应的变化，分析和推导了物流风险之间的逻辑关系，提供了事故中耦合效应及其演化过程的全貌，并识别出事故的关键原因及其耦合风险效应。对于港口危险化学品物流安全事故，所提出的结果不仅可以有效地分析事故原因，还可以为制定预防策略提供参考。
