一、总体研发思想
Ⅰ、Overall Research and Development Thoughts
轨道交通是一种低碳、节能、环保的绿色交通。 随着高速铁路时代的到来，为中国老百姓带来了 更加方便、快捷、安全、舒适的出行选择。
Rail transit is one kind of low-carbon, energysaving, environment-friendly green transportation. With the advent of high-speed railway age, it is more convenient, more comfortable, safer and faster for the common people to make a trip.
因为，轨道几何尺寸的制造精度、安装误差和刚度
变化是引起高速列车振动的根源。我们追求高速度 的过程，就是不断的提高轨道精度和轨道结构刚度 均匀性，不断克服振动的过程。
Since the manufacture accuracy of the rail geometry size, installation errors and rigidity change are the root cause to result in vibration of high-speed train. That we pursuit high speed is to keep improving the precision and longitudinal rigidity homogenization for the rail structure and overcoming the vibrations.

• CRTSIII型板式无砟轨道技术特点，正是针对上述技
术关键，吸取了以往各类无砟轨道优点，从而研发 的一种结构简单、施工便捷、稳定耐久、方便维修 的全新无砟轨道结构。
• In view of the key techniques mentioned above,
the technical characteristics of CRTSⅢ ballastless track which is developed as a kind of brand-new ballastless track of simple structure, convenient construction, easy maintenance, stable＆durable has the advantage of all kinds of previous ballastless track.

• 底座及支承层：桥上单元，隧道内混凝土长单元
（或直接采用隧底为基础），路基上为连续碾压 混凝土；
• Pedestal and supporting layer: bridge unit, long unit
路基基床底层
轨道板：路基纵连，桥隧单元；
Track slab: longitudinal-coupled subgrade, bridge ＆ tunnel unit
填充调整层：自密实混凝土；
Packed adjustment layer: self-compacting concrete
而高速铁道无砟轨道发展的技术路线，实质上就是始 终坚持不断地追求轨道的高平顺性，和轨道结构纵向 刚度均匀化的连续性。这是确保高速列车安全性和舒 适性最关键的核心技术。
Thus the development of high-speed railway ballastless track, in fact, mainly focuses on high smoothness for the orbit and continuity of longitudinal rigidity homogenization for the rail structure which are the most crucial key technology to maintain the security and comfortability of highspeed train..
