摘要:
［目的］我国城市轨道交通车辆ISA(独立安全评估)仍处于初步发展阶段，尚未形成较为完善的理论和规范化的标准，在专业化、系统化等方面仍存在不足，因此需对城市轨道交通车辆ISA策略进行研究。［方法］结合国内已开通运营和在建的城市轨道交通FAO(全自动运行)项目，以车辆系统隐患识别和风险管控为中心，对整车设计、制造与试验验证等各阶段的安全评估活动及安全证明体系要点进行了ISA。重点对FAO项目车辆特殊风险进行了ISA，评估内容主要包括安全文档评估、特殊风险安全评估及安全审计，且贯穿整个车辆建设工期。［结果及结论］国内部分已完成车辆ISA的城市轨道交通FAO项目表明，车辆系统相关的风险控制已达到可以接受的程度，在评估策略、评估方法及评估报告等方面都积累了一定的理论和实践经验，但在专业化和系统化等方面仍存在不足，需完善车辆ISA体系，形成我国车辆ISA的标准。
Abstracts:
［Objective］ China′s independent safety assessment (ISA) on urban rail transit vehicles is still in its initial development stage in that the relatively complete theories and standardization remain to be formed, and there are still deficiencies in specialization, systematization and other aspects. Therefore, it is necessary to study the strategy of ISA on urban rail transit vehicles. ［Method］ In view of the FAO (fully automatic operating system) urban rail transit projects opened for operation and under construction in China, and with focus on hidden hazard identifying and risk control in vehicle system, ISA is conducted on the safety assessment activities and the key points of the safety certification system at stages of vehicle design, vehicle manufacturing, and test verification. Focusing on the special risks of vehicles in the FAO projects, ISA mainly includes safety document evaluation, safety assessment on special risk, and safety audit, and runs through the entire vehicle construction period. ［Result & Conclusion］ Some of the FAO urban rail transit projects in China that complete the vehicle ISA show that the risk control related to the vehicle system is acceptable. Theoretical and practical experience in evaluation strategies, methods, and reports is accumulated. However, deficiencies still exist in specialization and systematization. It is necessary to improve the vehicle ISA system and form corresponding ISA standards for China.
