前言
本标准以球型支座的研究设计、运营养护经验为基础,参考了 1993年 8月欧洲标准化委员会第
167技术委员会(CET167)颁布的结构物支座标准草案第七篇“球型和柱型聚四氟乙烯支座”和第
二篇“滑动部件”、英国标准 B5400《钢桥、混凝土桥及结合梁桥》第九篇“桥梁支座”,以及德国工业标
准DI4141第12部分“结构物支座—滑动支座(草案)”的规定,首次制定而成。
本标准的附录 A 和附录 B是标准的附录。
本标准由铁道部科技教育司提出。
本标准由铁道部标准计量研究所归口。
本标准由铁道部科学研究院铁道建筑研究所负责起草。
本标准委托铁道部科学研究院铁道建筑研究所负责解释。
本标准主要起草:庄军生、张士臣
