Description
技术领域technical field

背景技术Background technique
我国早期修建的如南京长江大桥等均采用明桥面结构形式，轨道结构采用Ⅰ类木枕结构，枕长3m，断面为160×220mm。但由于既有木枕较容易开裂，耐腐蚀性差和开裂，结构寿命短，传统木枕轨道结构逐步在淘汰。今年来国铁、地铁、有轨电车大量铺设无砟轨道结构。目前无砟轨道主要以现场浇筑为主，圬工量大、施工繁琐、进度慢、对钢桥列车运行冲击振动较大，轨道结构几何状态难以保证。随着高铁技术发展，我国又相继研发了CRTS I型、CRTSⅡ型、CRTSⅢ型板式无砟轨道结构。高铁板式无砟均为单元结构，通过凸形挡台、限位凹槽及砂浆层传递等形成复合体系，并传递列车荷载，但该种无砟轨道结构复杂、造价较高，不太适用于一般国铁、地铁、有轨电车，也不适用于钢桥等特殊结构。The early constructions in my country, such as the Nanjing Yangtze River Bridge, all adopted the open bridge deck structure, and the track structure used a Class I wooden sleeper structure, with a sleeper length of 3m and a cross-section of 160×220mm. However, due to the fact that the existing wooden sleepers are easy to crack, have poor corrosion resistance and cracking, and have a short structural life, the traditional wooden sleeper track structure is gradually being eliminated. This year, a large number of national railways, subways, and trams have laid ballastless track structures. At present, the ballastless track is mainly poured on site, which involves a large amount of masonry, cumbersome construction, slow progress, large impact and vibration on the steel bridge train running, and difficult to guarantee the geometric state of the track structure. With the development of high-speed rail technology, my country has successively developed CRTS I, CRTS II, and CRTS III slab ballastless track structures. High-speed railway slab-type ballastless is a unit structure, which forms a composite system through convex baffles, limit grooves, and mortar layer transmission, and transmits train loads. However, this kind of ballastless track has a complex structure and high cost, and is not suitable for General national railways, subways, and trams are not suitable for special structures such as steel bridges.
因此有必要通过合理设计提供一种新型的无砟轨道体系，使其在确保可靠的支撑结构，减轻无砟轨道的恒载，保持良好轨道状态的前提下能方便运营维护，减小维修工作量，降低投资。Therefore, it is necessary to provide a new type of ballastless track system through reasonable design, so that it can facilitate operation and maintenance and reduce maintenance workload under the premise of ensuring a reliable support structure, reducing the dead load of ballastless track and maintaining a good track condition , reduce investment.
