先张预应力CRTS Ⅲ型无砟轨道板预制施工技术研究

Construction Technology Research on the Prefabricating of CRTS Ⅲ Type Ballastless Track Slab with Pretensioning Method

先张预应力法在CRTSⅢ型无砟轨道板中的应用具有较为明显的优势,不仅提高了我国高铁知识产权的自主化程度,同时也为我国高铁"走出去"战略的实施提供了强有力的技术支持。论文介绍了CRTSⅢ型无砟轨道的结构特点,分析了其工艺特点与关键技术,以供参考。

The application of pretensioning method in CRTS Ⅲ ballastless track slab has obvious advantages,which not only improves the degree of independence of intellectual property rights of high-speed rail in China,at the same time,it also provides strong technical support for the implementation of the "going out" strategy of high-speed rail in China.This paper introduces the structure characteristics of CRTS Ⅲ ballastless track slab,analyzes its technological characteristics and key technology,for reference.
