摘要

城市轨道交通车辆故障可能导致乘客伤亡的风险，为保证运营的安全，需对车辆系统的风险进行评估。文章详细阐述了危害与可操作性研究（HAZOP）方法及其实施步骤，重点介绍危害分析过程中对初步危害、（子）系统危害、接口危害、操作与支持危害等4个阶段的分析过程。采用危害与可操作性进行危害分析，结合风险矩阵，利用最低合理可行（ALARP）准则进行风险评估，对初始危害的风险等级进行评估，针对不可接受的初始风险，从设计、制造以及运营操作维护等方面增加合理的减轻风险措施，使其残余风险达到可接受的程度。应用实例表明了该方法的可行性。

Abstract

In order to ensure the safety of operations, the risks of operation accidents such as fatality must be assessed, which were caused by failures of urban rail transit rolling stock system. The methods of hazard and operability study (HAZOP) and its implementation steps were described in detail, with emphasis on the four following stages of hazard analysis, preliminary hazard, (sub) system hazard, interface hazard, operation and support hazard. HAZOP combined with risk matrix was used to preliminary hazard analysis, and the as low as reasonably practicable (ALARP) criteria was applied to assess the risk level of the preliminary hazards. Reasonable measures in terms of design, manufacturing, and operational maintenance to mitigate unacceptable preliminary risks should be added to make sure the residual risks were acceptable. The feasibility of the method was indicated in the practical application.
