【摘要】 本文以安全系统工程中的危险源理论为理论基础，根据环境风险评价的程序，对散装液体化学品码头区域环境风险水平进行了综合评价。 散化码头区域环境风险评价是对区域内多个风险因素的综合评价。在定量评价区域内多个风险因素的基础上，得到区域环境风险的综合指数或风险度，为控制和管理风险提供科学依据。本文将散装液体化学品码头区域环境风险评价分为风险源项辨识与分析、燃爆及毒物泄漏事故后果影响分析以及区域环境风险综合评价等部分。 对散化码头进行风险源项分析，目的是确定散化码头各个评价单元的风险因素和风险类型。通过对各种类型的风险因素进行定性和定量分析，并对各风险因素的危害后果进行判别和评估，可以确定散化码头各类危险源的危害强度及作用范围及其风险等级水平。 散化码头发生火灾爆炸及毒物泄漏事故后果影响分析包括经济损害影响评价、健康损害影响评价和环境损害影响评价三部分。本文对于经济损害的评价采用道氏法；健康损害影响评价又包括燃烧、爆炸和毒性三方面的影响。本文由于篇幅所限，对于事故造成的散化码头区域水域、大气和陆域的损害后果及其影响，未进行深入探讨。 散化码头区域环境风险综合评价是考虑到多种风险因素的差异，对各风险因素的风险度进行加权综合，并从它们对于区域环境、人群健康等多方面的影响程度出发，对散化码头储运系统的安全水平或等级进行总体评价的过程。本文运用模糊工程理论中的标准可加性模型对散化码头进行区域环境风险评价。更多还原

【Abstract】 Based on the theory of hazardous resources in Safety System Engineering and applying the relevant principles in Environment Risk Assessment,this paper makes a comprehensive assessment of environment risk on terminals of liquid chemicals in bulk. According to the quantitative analysis of many risk factors in a region of chemicals terminal,exponents of regional environment risk degree are concluded,which can provide the risk controlling and management with scientific guidelines.The chemical cargos stored and transported at terminals have the potential danger of fire,explosion and the danger of leakage and diffusion of poison. In this thesis,the synthetic risk assessment is divided into three parts,namely recognition and analysis of hazardous resources,analysis of accident aftereffects and the comprehensive evaluation as well.To distinguish the risk factors and the class of risk of each assessment unit in chemicals terminal,this paper conducts qualitative and quantitative analysis of dangerous characteristics of combustion,explosion and toxicity of chemicals in bulk. The overall risk degree of all types of hazardous resource units and the intensity of harm can be obtained on the basis of above analysis.The analysis of accident after effects includes mainly two aspects:economic damage effect and health damage effect. The economic damage effect assessment is conducted with the method of Fire & Explosion Index (F&EI). The health damage effect assessment indicates personnel safety risk.In view of different risk factors and the interaction among them,this paper applies Standard Additive Model of Fuzzy System Engineering to environment risk assessment on chemicals terminal. The result of assessment reflects the integer risk level of chemicals terminal,which can do benefit tosafety management and decision-making.更多还原
