Pot bearing is one of the most widely used bearings. China Railway standard of pot bearing is a professional standard established on China's reality, while European standard is taken as reference. This paper, the differences and characteristics between China Railway standard and European standard of pot rubber bearing are discussed by means of comparative analysis according to experience of application and actual needs. The results point that some parts of the two standards are lagged and can not satisfy the design and application needs of the bearing; in addition, some contents of the standards are unreasonable, with which the application of new technology and new materials are blocked; and so, the two standards of pot rubber bearing are really needed to be revised. Finally, improvement advices for China Railway standard of pot rubber bearing are proposed based on the results of the analysis in the paper.%盆式支座是当今应用最为广泛的支座之一,其铁路行业标准则是借鉴欧洲技术,综合中国实际而制定的行业标准.研究铁标和欧标的差异和特点,根据应用的经验和实际需求,对盆式支座铁路标准提出完善建议,在铁路行业大发展的今天,对线路安全和建造成本控制均具有重要的意义.通过对铁标与欧标的对比分析,目前的盆式支座铁标和欧标已有部分已滞后,不能满足支座的设计、应用要求.此外,亦有部分内容不合理,有碍于新技术和新材料的应用.因此,盆式支座铁标和欧标亟待修订.据此,对盆式橡胶支座铁路标准提出了修订建议.
