无砟轨道具有稳定性高、刚度均匀性好、结构耐久性强、维修工作显著减少等优点,同时无砟轨道的应用从根本上改善了列车走行的基础条件,实现了列车运行的平稳性、安全性、舒适性。近年来,我国也先后在京津、武广、郑西等高速铁路全面采用无砟轨道施工,设计理念和施工工艺日趋成熟和完善。雷达2000型双块式无砟轨道 The ballastless track has the advantages of high stability, good uniformity of rigidity, strong structural durability and significant reduction of maintenance work. The application of the ballastless track fundamentally improves the basic conditions of the train running, realizes the smooth operation of the train, Security, comfort. In recent years, China has successively adopted the ballastless orbit construction in the high-speed railway such as Beijing-Tianjin, Wu-Guang and Zheng-Xi, and the design concept and construction technology have matured and been perfected.
