前言我国自1958年开始研究混凝土轨枕板新型轨道,经历了研究、选型、试铺和扩大试铺等各个阶段,至1980年底已在铁路线路上铺设轨枕板轨道169公里。其中铺在繁忙干线上有12公里,铺在隧道内的有33公里,铺在车站站场等线路的有7公里。铺设时间最长的在繁忙干线上达十五年半,铺在隧道内的也有十五年。二十多年的研究工作和十五年以上的铺设、运行经验已表明轨枕板轨道是适合我国铁路运输发展的一种较好的“少维修”轨道结构型式 Foreword Since 1958, China began to study the new type of orbit of concrete sleeper. It has undergone various stages of research, selection, testing and expansion of test shops. By the end of 1980, 169 km of rail sleepers have been laid on railway lines. Among them, there are 12 kilometers on the busy trunk road, 33 kilometers in the tunnel and 7 kilometers in the line of the station and station. The longest laying time was 15.5 years on the busy trunk road and 15 years in the tunnel. More than 20 years of research work and more than 15 years of laying and operating experience have shown that the sleeper rail is a good “less maintenance” orbit structure suitable for the development of China’s rail transport
