摘要
研究目的:郑徐高速铁路是我国CRTSⅢ型先张板式无砟轨道扩大应用的首条试验线,CRTSⅢ型板式无砟轨道的设计理论、结构设计、工程材料、建造技术等方面都需要系统创新,轨道结构及接口优化、轨道板制造、岔区无砟轨道、路基防水层优化、自密实混凝土制备及施工、布板及精调等关键技术都需要进一步深入研究,本文旨在丰富、发展和完善CRTSⅢ型板式无砟轨道技术体系。研究结论:(1)形成了具有自主知识产权的CRTSⅢ型板式无砟轨道设计、制造、施工等成套技术;(2)郑徐高速铁路开通运营以来,无砟轨道系统状态良好,结构稳定,列车运行平稳、舒适;(3)本研究成果对于提升我国在高速铁路国际市场的竞争力和顺利实施我国高速铁路"走出去"发展战略具有重要意义。
Research purposes： Zhengzhou - Xuzhou High - speed Railway is the first test line for expanding application of CRTS Ⅲslab track pretensioning prestressed slab in China. The design theory, structure design, construction materials, construction technology and other aspects of CRTS Ⅲ slab track require innovation. There are plenty of problems in interface optimization, slab manufacturing, turnout ballastless track slab, subgrade waterproofing layer optimization, self- compacting concrete preparation and construction, slab layout and fine adjustment that need further study. The research purpose of this paper is to develop and improve the CRTS Ⅲ slab track technology system of high - speed railway. Research conclusions： （ 1 ） The complete technology system of CRTS Ⅲslab track design, manufacture, and construction has been formed. （2） Since the operation of Zhengzhou - Xuzhou High - speed Railway, ballastless track has been in good condition, and the train has been running smoothly and comfortably. （3） The research results have an important significance in improving our competitiveness in the international market and carrying out the go global strategy.
