Abstract : This is the classification of slag orbit, the advantages and disadvantages, development situation, no residue the requirement of track were introduced briefly, the China tianjin high-speed railway, the beijing-tianjin railway is China's first railway passenger special line, the article, and the beijing-tianjin inter-city used at the board of the introduction, describes the laid of prefabricated borg board and board to track the production process. Finally, the article briefly introduces the ballastless-rail orbit in the research and application of high speed railway and no ballastless track design key technology, including no of ballastless track structure design and the lower part of the orbit of ballastless-rail based (Bridges, tunnels, transition section).

引言
无砟轨道又作无碴轨道。在铁路上,“砟”的意思是小块的石头。路砟有几个作用:加大受力面从而分散火车压力帮助铁轨承重、减少噪音、吸
