摘要:
目前城市轨道交通一般采用现浇无砟轨道，存在效率低且施工精度难以保证等问题。而高铁CRTSⅢ型板式无砟轨道施工精度高、效率高且技术成熟，因此国内首次将高铁技术引入城市轨道交通，在高铁CRTSⅢ型板的基础上研发了适用于城市轨道交通的预制板式轨道，以提高城市轨道交通铺设质量。为此，从城市轨道交通预制板式轨道结构设计、理论计算、室内试验、轨道板制造工艺及施工工艺等方面进行了系统、全面研究，研究成果已广泛应用于上海轨道交通，可供同类型工程参考。
Abstracts:
Currently, urban rail transit generally adopts cast in situ ballastless track, which has problems of low accuracy in construction, low efficiency. While high speed railway CRTSⅢ slab ballastless track has high precision in construction, high efficiency and mature technology. Therefore high speed railway technology is introduced into urban rail transit domestically for the first time. On the basis of high speed railway CRTSⅢ slab, precast slab track applicable to urban rail transit is developed, to improve the quality of urban rail transit laying. Systematic and comprehensive research is conducted in urban rail transit precast slab track structure design, theoretical calculation, indoor test, manufacturing and construction technology of track slab. The research results have been widely applied in Shanghai rail transit and can be used as reference for similar projects.
