If the unit structure is adopted, when the train passes on it, the supporting force at the end of slab and binding force are not enough so that the vertical displacement at the end of slab is comparatively large, because of the low surface rigidity of the subgrade, which results in vibration source that has great influence on the safety and convenience of the high-speed train. 中通衡熟啊哺众杀槽渔嚣福解鞘巧介踊奴八禾些劣浪医妆澎蛾尝讳椭吹钢CRTSII型板式无砟轨道建造全新理念CRTSII型板式无砟轨道建造全新理念纵连结构可有效分散板下应力集中，降低应力峰值，提高轨道结构的整体性，增大轨道结构的连续刚度，可最经济、最合理、最有效的克服路基表面刚度降低所带来的振动问题。The longitudinal-coupled structure can distribute stress concentration effectively and reduce stress peak to improve the integrity of the rail structure and increase its continuous rigidity.
