摘要:: 自20世纪60年代开始，我国开始在普速铁路隧道地段开展支承块式等多种形式无砟轨道的试验及应用；20世纪90年代，开始进行高速铁路无砟轨道的研究，经过秦沈、遂渝等无砟轨道试验段铺设及试验，形成了时速200 km级无砟轨道建造成套技术；21世纪初，通过引进消化吸收再创新，形成了CRTSⅠ型板式、CRTSⅡ型板式和双块式无砟轨道，并自主研发了CRTSⅢ型板式无砟轨道，在我国高速铁路建设中广泛应用，运营里程已超过2.1万km。目前，我国正在积极推进智能建造、全生命周期管理等技术在无砟轨道中的应用。随着技术研究和工程应用的不断深入，我国无砟轨道技术必将得到进一步的发展和完善。

Abstract:: From the 1960s, China began to carry out the experiment and application of various forms of ballastless track, such as supporting block type, in the tunnel section of conventional railway. In the 1990 s, it began to conduct research on ballastless track of high-speed railway. After the laying and testing of ballastless track pilot sections in Qinhuangdao-Shenyang and Suining-Chongqing High-speed Railways, a complete set of technologies for ballastless track construction with a speed of 200 km/h was formed. At the beginning of the 21st century, through the introduction, digestion, absorption and innovation, the CRTSⅠ slab, CRTSⅡ slab and double-block ballastless track were formed, and the CRTSⅢ slab ballastless track was independently developed, which is widely used in the construction of high-speed railway in China, the operating mileage has exceeded 21 000 kilometers. At present, China is actively promoting the application of intelligent construction, full life cycle management and other technologies in ballastless track. With the development of technology research and engineering application, China’s ballastless track technology will be further developed and improved.
